Can a bad mass air flow sensor cause loss of power?
As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on.
Can a MAF sensor be bad and not throw a code?
2. Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
What does code p0102 mean on the ECM?
Mass or Circuit Airflow (MAF) Circuit Low Voltage Input What Does P0102 Mean? The Mass Airflow (MAF) sensor measures the amount of air entering the engine. When code P0102 is set, there is a low voltage output to the ECM, PCM, or ECU depending on your car type (check your owner’s manual for your specific car).
What does the code p0102 mean on a Honda Accord?
All our repairs are backed by our 12-month / 12,000-mile warranty. The code P0102 code is often associated with P0100, P0101, P0103 or P0104 trouble codes as they are closely related. P0102 is the general code for a problem with the Mass Airflow (MAF) Sensor having a low voltage output to the Engine Control Unit (ECU).
What causes OBD-II scanner error code p0102?
A vacuum leak will allow air to escape instead of being drawn into your engine. Repair or replace the necessary tract or components to create a firm seal. Once you restore your air intake system, reset the code and check again to see if you’ve solved the OBD-II scanner error code P0102 problem.
How to test the GM MAF sensor ( p0100 )?
P0101: Mass Air Flow (MAF) Sensor Circuit Range/Performance Problem. P0102: Mass Air Flow (MAF) Sensor Circuit Low Input. P0103: Mass Air Flow (MAF) Sensor Circuit High Input. Lean and/or Rich Diagnostic Trouble code (s).
