What does the GMC code p0102 mean?

P0102 GMC Meaning The Mass Air Flow (MAF) sensor measures the amount of air ingested by the engine. The direct measurement of the air entering the engine is more accurate than calculating the airflow from the Manifold Absulte Pressure (MAP), the Intake Air Temperature (IAT), and the engine speed (speed/density).

What to do if your Mercedes has a code of p0100?

Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle.

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

How often does GMC Sierra set p0446 code?

I have a 2002 GMC Sierra with a 4.3L Vortec and 32K miles on it. It sets the P0446 code about every 3 months or so, pretty much like clock work. I have the Haynes manual bought from Auto Zone.

What does trouble code p0443 mean on a car?

P0443 trouble code symptoms could be just an malfunction indicator lamp (MIL) illumination. There may be no drivability problems at all. But, it’s also possible to have a lean condition or a rough running engine if the purge valve is stuck open.

What causes a p0443 purge control circuit?

To cause a P0443, there has to be a problem with the purge control CIRCUIT , not necessarily the valve. Usually they are a unit housing the valve and the solenoid as an assembly. Or it could be comprised of a separate solenoid with vacuum lines to a purge valve. That said, it could be any of the following:

What does the p0442 code on a GMC Sierra mean?

The EVAP system captures all fuel vapor from the fuel tank and sends them to the engine’s intake in order to be ignited in the normal combustion process. When the GMC Sierra’s computer detects that the EVAP systemic not holding any pressure, it will throw the P0442 code.

Why does my Chevy Colorado have a p0446 code?

Vapor Canister Purge Valve – One of the most common causes of the P0446 code is the vapor canister purge valve. It’s really easy to replace. There are a few clips that you need to find and remove. Evap System Hose – The hose that carries the fuel vapor from the fuel tank to the intake manifold can begin to leak. This will cause the P0446 code.

This trouble code references a number that is given to you when you plug your Sierra into a OBDII scanner. P0446 Indicates that there is a fault in the evaporative emission control system. It often appears with other codes, such as P0420, P0441, or P0440.

What causes a p0107 DTC to be set?

A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low. Anytime the MAP sensor signal is low the vehicle will likely have a very difficult time starting. Other symptoms may include: MIL (Malfunction Indicator Lamp) illumination

What is the OBD 2 fault code p0107?

OBD II fault code P0107 is defined as “ Manifold Air Pressure/Barometric Pressure Circuit Low Input”, and is set when the PCM (Powertrain Control Module) detects a signal from the MAP (Manifold Air Pressure Sensor) that falls outside of the expected value for the reigning engine load or throttle position,…

What does the p0107 code in OBD mean?

What the P0107 code means. P0107 is the general code for a problem with the MAP circuit sensor having too low voltage input to the Engine Control Unit (ECU). This means the voltage input to the ECU is .5 volt or less which means that it is not in the correct lower range for proper engine operation.
