Trouble P0101 - Mass Air Flow Sensor Range/Performance

Standard fault codes for the Lada Kalina are a set of alphanumeric codes that describe problems associated with the car's electrical systems. Due to the high cost of specialized service, experienced drivers decide to troubleshoot problems on their own. The car is equipped with a self-diagnosis system. On-board equipment does not stand out for its increased accuracy. The codes found usually only indicate the circuit where the fault is located. The system is unable to mark the damaged element. The following is a description of errors for simple versions, Cross and other modifications.

Causes of error P0101

• The mass air flow sensor sends a signal to the engine control module (ECM) that is out of range.
• The mass air flow sensor is not functioning properly due to damage or malfunction.
• Electrical wires or the MAF sensor itself are located too close to higher voltage components (such as the alternator, ignition wires, etc.) which can cause interference that affects the signal sent to the vehicle's ECM.
• The problem could also be damaged vacuum hoses, which can lead to various problems and other error codes.
• The MAF sensor must operate within a certain range to be able to send the correct signals to the vehicle's ECM, which is necessary for proper engine operation.

Tips to Avoid P0101 in the Future

Dirt and carbon deposits in the engine can cause many problems, including trouble code P0101. Check the air filter regularly and make sure it is installed correctly when replacing it. Regular maintenance of your engine fluids, especially oil, will also help keep your engine clean.

This code can also be caused by worn wire insulation. Make sure all wires are kept away from ignition coils and other potential sources of damage.

How does a mechanic diagnose a P0101 code?

When diagnosing this error, the mechanic will do the following:

• Connects the OBD-II scanner to the vehicle's diagnostic connector and reads all stored data and error codes
• Visually inspect the engine, then clear the fault codes from the computer's memory and test drive the vehicle to see if P0101 appears again.

If the error code appears again:

• Check the electrical connector of the mass air flow sensor for looseness.
• Check the electrical wires related to the mass air flow sensor for damage
• Find out if electrical wires or the MAF sensor itself are located too close to higher voltage components

Why does a malfunction occur?

If the vehicle ECM detects a voltage in the throttle position sensor “A” circuit that is less than 0.2 volts, we can talk about error P0122. At the same time, it is stored in the vehicle’s memory. Code P0122 does not always mean one error, but several. Among the main reasons for the occurrence of error P0122 are the following.

1. Unreliable and weak throttle position (TPS) setting.
2. The appearance of short circuits in the circuit of sensor “A”, which is responsible for the throttle valve or accelerator pedals (TPS), in relation to ground or other wires.
3. Malfunction of the sensors that regulate the position of the throttle valve and “A”, which is responsible for the accelerator pedals (TPS).
4. The appearance of an open circuit in the sensor responsible for the throttle position, or poor quality power supply.
5. The appearance of breaks in the wiring harness of the sensor responsible for the throttle valve or shorts associated with ground or other wires.
6. There is damage in the computer (PCM).

Common mistakes when diagnosing code P0101

• The most common mistake when diagnosing a P0101 code is to hastily replace the MAF sensor without first checking the associated electrical wires and connector for damage.
• It is also a mistake to neglect to check the mass air flow sensor for excessive carbon buildup before replacing it. Sometimes the problem can be solved by cleaning the sensor using a special cleaner designed for mass air flow sensors.
• Another mistake is neglecting to check the vacuum hoses for wear and damage.

Errors during diagnostics

In order to accurately determine the cause of the error and methods for eliminating it, diagnostics are carried out. It can be done with the help of a car mechanic or yourself if you have the proper experience. An OBD-2 scanner is used for operation. Common errors that occur when diagnosing a P0122 code include:

• sensor “A”, which is responsible for the throttle valve, connector and electrical wires, is not inspected;
• the scanner is not checked, the code is not cleared from the computer memory, the system is not re-checked before repair;
• sensor “A”, responsible for the correct position of the throttle valve, is not inspected properly;
• The voltage of sensors “A” and “B”, responsible for the throttle valve, is not checked before and after repair work.

How serious is P0101?

• When the P0101 error code appears, there are usually no serious problems with the vehicle's drivability, however, if this code is detected, it is recommended that you contact a qualified technician as soon as possible to diagnose and repair the error.
• Under certain circumstances, damage or failure of the mass air flow sensor can lead to increased fuel consumption, unstable engine operation, and problems starting the engine. In some cases, damage to internal engine components may occur.
• Often, if the Check Engine Light comes on immediately after starting the engine, the OBD-II system can be reset and the vehicle will continue to operate normally.

What repairs can fix the P0101 code?

To resolve error P0101, you may need to:

• Check for the presence of the error code using a scan tool, clear the code from the computer's memory, and test drive the vehicle to see if the P0101 code appears again

If the error code appears again:

• Reconnecting, Repairing, or Replacing the Mass Air Flow Sensor Electrical Connector
• Repair or replacement of electrical wires related to the mass air flow sensor
• Replacing worn or damaged vacuum hoses

Additional comments for troubleshooting P0101

• Many high-mileage vehicles have short-term problems with sensors, which usually occur when the engine is started or the transmission is subjected to prolonged stress.
• Often, if the Check Engine Light comes on but the vehicle continues to operate normally, the OBD-II system can be reset and the problem will be resolved. This is why it is important to check for an error code using a scanner and clear the code from the computer's memory before performing any repair work.

On which cars is this problem most common?

The problem with code P0101 can occur on different machines, but there are always statistics on which brands this error occurs more often. Here is a list of some of them:

Diagnosis and problem solving

Carefully check the Throttle Position Sensor (TPS), wiring connector and wiring for opens, etc. Repair or replace as necessary to resolve P0122.

Check the voltage at the TPS (see your vehicle's service manual for more information). If the voltage is too low, this indicates a problem. Replace the sensor if necessary.

If recently replaced, the TPS may need to be adjusted. On some vehicles, installation instructions require proper adjustment (see repair manual for details).

If there are no symptoms, the problem may be intermittent and cleaning the code may temporarily resolve it. In this case, you should definitely check the wiring to make sure that it is not rubbing, worn out, etc.

Other trouble codes related to the TPS sensor and circuit: P0120, P0121, P0123, P0124.

Primary sources of sensor failure

The most obvious reason for the incorrect operation of such a device is wear. Moreover, the wear of different parts has different effects on the system.

• Erasing conductor coating. Therefore, it becomes impossible to fix the voltage indicator.
• Exhausted wear reserve of the moving element of the sensor. When the gap between it and the axle conductor becomes too wide, contact between them is lost. At the same time, the check does not pop up. You can guess about it by the intermittent operation of the engine in different modes.
• Oxidation, rust coating, accumulation of a layer of contamination on the contacts.

After detecting such design changes, you have no choice, the device cannot be repaired, it must be replaced. Of course, it is better to purchase a contactless device. It is much more reliable, because it has no rubbing elements.

Common errors on Lada Granta

But these are not the only mistakes that Lada owners encounter. Errors occur on both 8- and 16-valve engines. Here are some of them:

• p0503 – the speedometer is malfunctioning (read more about speedometer failure using the example of a Volkswagen Bora with an automatic transmission);
• p0422 – catalyst is clogged (what to do if the catalyst is troit);
• p0600 - the immobilizer does not respond, you should check the wiring or read what to do if the immobilizer does not pump the fuel pump;
• error p1701 on the Grant-automatic - faulty power supply circuit.

These are the main codes that Lada Granta owners may encounter. You should not neglect them; you must immediately take measures to eliminate them.

Why do you need a damper with a sensor and how does it work?

In injection cars, the air and fuel supply is controlled using an electronic unit, into which information from numerous sensors and systems flows. Thus, the angle of the damper is controlled by its position sensor. The choice of the deflection angle is necessary for the formation of an optimal air-fuel mixture and normal engine operation (without jerking and loss of power). Throttle valves on older cars were driven by a cable that was connected to the accelerator pedal. Modern dampers are deflected using a drive motor.

Please note that some remote sensing devices have not one, but two sensors. Accordingly, they will have more possible errors. There are two types of sensors - contact, they are also called potentiometers or film-resistive and non-contact, another definition is magnetoresistive.

Regardless of the type of TPS, they perform the same function - they transmit information about the damper deflection angle to the electronic control unit. In practice, this is realized by converting the damper deflection angle into a constant voltage value, which is a signal to the ECU. When the throttle is completely closed (idling), the voltage is at least 0.7 Volts (may vary for different cars), and when fully open - 4 Volts (may also differ). The sensors have three terminals - positive (connected to the car battery), negative (connected to ground) and signal, through which variable voltage is transmitted to the computer.

What are the effects of TPS malfunctions?

1. On the idle speed parameters. Injectors do not have a unified system for this stroke in the form in which we are accustomed to seeing it in carburetor engines. All parameters of this mode are calculated only from TPS readings. Unstable speed, interrupted engine operation.
2. Increased fuel consumption. The device sends a dubious signal, which is perceived by the ECU as a closed damper (although in reality it is open). Parameters are included that imply an increase in the proportion of fuel in the mixture. It turns out that the car operates as usual, with a stable shaft rotation speed, and consumes much more gasoline.
3. As you pick up speed, you feel dips and the car jerks noticeably.
4. When the position of the accelerator pedal remains unchanged, the car jerks, and when the pedal is suddenly released, the engine completely stalls.
5. The car does not pull, you feel a loss of power.

The Check Engine button turns on, indicating that the error has been detected.

Error P2135 dpdz

Along with this error, the ECU produces some others that reflect deviations from the norm in the operating parameters of the throttle valve and their sensors - P0120, 0122, 0123, 0220, 0223, 0222, 01578.

The test comes down to measuring the voltage of the sensor signal, as well as the resistance of the wires, especially the state of the ground pin of the electronic unit.

Possible reasons could be:

1. Poor condition of the “mass”. If necessary, clean, solder, eliminate breaks
2. Faulty relay. This problem can be solved by replacing the part (it is better to purchase a part from a European manufacturer with a current of 40 amperes)
3. Unsatisfactory condition of the sensor's electrical outputs. You can try bending them in the connector, this is often enough.
4. A short circuit is detected between VTA contacts 1 and 2. Voltage measurements in this zone show a deviation from the same 5V by more than 0.2V
5. Problems in the electromechanical throttle mechanism (EMDU). The malfunction is eliminated by replacing the device.
