What would cause a P0102 code?

What causes the P0102 code? The MAF Sensor has low voltage output problems which may have several causes. The source of the problem is the sensor range voltage is lower than normal or required by the ECU to function properly. The MAF sensor can also be dirty or partially plugged with carbon causing a low reading.

Can you trick a mass air flow sensor?

How much does it cost to replace a mass air flow sensor? The average cost for mass airflow sensor replacement is between $291 and $305.

Can a vacuum leak cause a p0102 code?

This is commonly caused by a blocked air filter, a vacuum leak, a blocked catalytic converter or a dirty, damaged or failed mass air flow sensor.

What should a MAF read at idle?

With the engine at idle, the MAF’s PID value should read anywhere from 2 to 7 grams/second (g/s) at idle and rise to between 15 to 25 g/s at 2500 rpm, depending on engine size. Most manufacturers provide specifications for air flow at idle; some will provide specifications at several engine speeds.

How do I reset my mass airflow sensor?

Check if the engine light is still on after the Mass Air Flow Sensor was replaced. The entire system can be reset by unhooking the battery and leaving it unhooked for 10 minutes. Keeping the battery unhooked for longer than 10 minutes won’t hurt anything.

Is P0137 upstream or downstream?

Code P0137 triggers when the PCM detects that the signal from oxygen sensor 2 on Bank 1 is below a specific value for a certain amount of time. There are two O2 sensors in your vehicle. The sensor located before the catalytic converter is the upstream sensor, also known as Sensor 1.

How do you bypass a mass airflow sensor?

How to Bypass the Cold Air Intake Sensor

Turn off the ignition of your vehicle and open its hood.
Disconnect the negative battery cable (red).
Grasp the wire harness that connects the MAF sensor to the power unit in the engine compartment and gently pull it out of the MAF sensor.
