What does diagnostic code P0102 mean?
Mass Airflow
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 does p101 code mean?
P0101 is a diagnostic trouble code (DTC) for “Mass Airflow (MAF) Circuit Operating Range or Performance Problem”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does the p0202 OBD-II Diagnostic Code mean?
The P0202 code is a general OBD-II diagnostic trouble code (DTC) associated with the injector circuit. Note: This code may be seen with P0200, P0201, or P0203-P0212. P0202 may also be seen with misfire codes and lean or rich condition codes. What the P0202 code means
When does the ECM set the p0202 code?
P0202 indicates that the ECM has detected a malfunction for the cylinder 2 injector circuit. The code is set once the ECM detects out-of-range voltage or resistance.
What causes a p2149 fuel injector supply voltage code?
Causes for this P2149 fuel injector group supply voltage code may include: Defective or damaged fuel injector (s)
What to do if you get trouble code p2149?
If the trouble codes or customer concern is induced during the wiggle test on any other cylinders (other then P0202/P0207), replace the affected injector connector pigtail with P/N 88988963. This replacement pigtail can be used to repair any cylinder except number 2 and number 7.
When do I need to fix trouble code p0102?
A trouble code P0102 is triggered when there is low airflow registered by the Mass Air Flow, or MAF, sensor. When this happens, you need to know how do I fix trouble code P0102?
What does p0102 mean on the MAF sensor?
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). P0102 Symptoms
What does the p0202 code on a cylinder 2 mean?
P0202 may also be seen with misfire codes and lean or rich condition codes. P0202 indicates that the ECM has detected a malfunction for the cylinder 2 injector circuit. The code is set once the ECM detects out-of-range voltage or resistance. The malfunction causes the ECM to set a Check Engine Light and a failsafe mode.
What to do if your injector code is p2149?
If the vehicle had only injector circuit codes for P0202 or P0207 (with bank shutdown P2146 or P2149), and the wiggle test induces a P0202 or P0207 to reset, use bulletin number 05-06-04-047B to repair the injector connectors and install the injector harness support kit.
