What is the trouble code for a p0301 cylinder?
P0118 CTS, P0507 ERGvalve, P0301 misfire #1. Hi, Replaced CTS, ERG, cleaned throttle body, ck for vacuum leaks. When I start (cold or hot) immediately revs to 2000 rpm, in 10 sec will gradually come down to 1200rpm & stay there. throttle is fully closed and …
What does the Check Engine Light code p0101 mean?
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 does the code p0112 mean on the IAT sensor?
The P0112 code indicates that the IAT sensor is operating at a low voltage and reports a temperature of about 300 °F (149 °C). The P0113 code is caused by a high circuit voltage and means that the IAT sensor reports a temperature of about -38 °F (-39 °C). What is an Intake Air Temperature Sensor?
Why are the Pistons on my Duramax not working?
Low-quality castings from its suppliers and a reduced amount of meat present in the wrist pin area (thanks to the use of wrist pin bushings) are to blame for factory piston failure. In most cases, the cast-aluminum piston cracks along the center line of the wrist pin, as shown above.
What causes the OBD-II trouble code p0112?
P0112 is the OBD-II generic code that the engine control module (ECM) has recorded the IAT sensor input below the expected sensor range. What causes the P0112 code? If the output voltage is less than 0.18 V for 0.5 seconds or more, the ECM determines that there is a short in the sensor circuit, and sets trouble code P0112.
When does a PCM set a p0112 code?
If the PCM notices that the incoming air temp is unusually high, say, 300 degrees, when the engine temp is still relatively low, it will set a P0112 . There may be no noticeable symptoms of a P0112 code other than an MIL (Malfunction Indicator Lamp). However, a emissions test may reveal higher Nox readings depending on the type of IAT failure.
What causes a p0112 intake air temperature circuit?
Usually the P0112 is caused by a bad IAT (internally shorted or open or otherwise damaged), but it could also be: No reference voltage to the IAT sensor due to an open wire Excessively high intake air temperatures Short to ground on signal circuit
What does code p0122 on a TPS mean?
Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input What Does Code P0122 Mean? Code P0122 is triggered when your vehicle’s Engine Control Module (ECM) detects that your Throttle Position Sensor (TPS) circuit A is reporting an output voltage that is below its expected voltage.
