What is code po511?
What is code po511?
Error Code P0511 is defined as Idle Air Control Circuit. Meaning, the engine’s RPM is having an abnormal condition when idling, due to defective valves, faulty electrical wiring, or a severe leak.
What is idle air control Circuit?
Commonly called an idle air control (IAC) valve or idle speed control (ISC) valve, this device is used on many cable-operated throttle bodies to regulate the engine idle speed. This process is completed by regulating airflow through a bypass circuit around the throttle plate to increase or decrease idle speed.
What does the p0101 code on the MAF sensor mean?
Code P0101 means that the MAF sensor relays irrational or out of range readings. What Does the P0101 Code Mean? Diagnostic trouble code (DTC) P0101 code stands for “Mass or Volume Air Flow ‘A’ Circuit Range/Performance.”
What is the error code for mass air flow?
This error code is a generic code associated with MAF sensor circuit trouble codes, such as P0101, P0102, P0103 and P0104. The MAF is placed in the stream of intake air.
What happens when the p0102 code is set?
While you may technically still be able to drive when a P0102 code is set, you should not do so for long. An issue with the MAF sensor can cause your car to stall or run poorly—and that can be dangerous. What’s more, a faulty MAF sensor can damage other parts of your vehicle, such as the catalytic converter.
What is the trouble code for a MAF sensor?
Note: Some MAF sensors also incorporate an air temperature sensor, which is another value used by the PCM for optimal engine operation. Closely related MAF circuit trouble codes include P0100, P0101, P0102, and P0103. Photo of a MAF sensor:
Code P0101 means that the MAF sensor relays irrational or out of range readings. What Does the P0101 Code Mean? Diagnostic trouble code (DTC) P0101 code stands for “Mass or Volume Air Flow ‘A’ Circuit Range/Performance.”
What is the OBD code for mass airflow?
Error Code P0101: Mass Airflow Sensor Circuit Range/Performance Problem. The onboard diagnostic (OBD) code P0101 refers specifically to a Mass or Volume Airflow Circuit Range/Performance Problem. In a vehicle, the mass airflow (MAF) sensor measures the amount of air going into the engine through the intake.
When to use check engine light code p0101?
The mass air flow (MAF) sensor measures the amount of air entering the engine. Check engine light code P0101 is set when the measurement of air entering the engine by the mass air flow sensor is outside of the manufacturer’s specified range.

What causes a trouble code on a MAF sensor?
Possible Causes. Potential causes for this trouble code may include: Dirty or contaminated mass air flow sensor. Failed MAF sensor. Intake air leaks. MAF sensor electrical harness or wiring problem (open, shorted, frayed, poor connection, etc.)
