Showing matches for "oil leak".
P0093: Large fuel-system leak detected
Fuel pressure is dropping at a rate that the ECU interprets as a major leak or excessive internal loss.
P0442: EVAP system small leak detected
The fuel-vapor system cannot hold the small vacuum or pressure change expected during the leak test.
P0455: EVAP system gross leak detected
The fuel-vapor system has a large leak or cannot seal during its self-test.
P0456: EVAP system very small leak detected
The fuel-vapor system has a very small leak during the ECU's leak test.
P2279: Intake air system leak
The ECU detects extra unmetered air entering the intake system.
P0301: Cylinder 1 misfire detected
The ECU detected repeated combustion misfires on cylinder 1.
P0302: Cylinder 2 misfire detected
The ECU detected repeated combustion misfires on cylinder 2.
P0305: Cylinder 5 misfire detected
The ECU detects repeated combustion failure specifically on cylinder 5.
P2187: System too lean at idle, bank 1
The ECU detects a lean condition mainly at idle, where small air leaks have a larger effect on mixture control.
C1130: Chassis control or suspension pressure fault
A chassis or suspension control module has detected an implausible pressure, height, or control-state condition.
P0011: Intake camshaft timing over-advanced, bank 1
The intake camshaft is more advanced than the ECU expects for the current operating condition.
P0014: Exhaust camshaft timing over-advanced, bank 1
The exhaust camshaft position is more advanced than commanded or is slow to return to the expected position.
P0016: Crankshaft / camshaft timing correlation
The ECU sees the crankshaft and camshaft signals outside their expected relationship.
P0017: Crankshaft / camshaft timing correlation, bank 1 sensor B
The exhaust-camshaft and crankshaft signals on bank 1 are outside their expected relationship.
P0046: Turbocharger boost-control circuit range / performance
Turbo actuator or boost-control response is outside the range expected by the ECU.
P0068: Throttle body airflow correlation
Throttle position, manifold pressure, and measured airflow do not agree with one another.
P0087: Fuel rail pressure too low
Measured fuel pressure fell below the pressure requested by the engine controller.
P0101: Mass-air-flow signal range / performance
Airflow reported by the MAF sensor does not agree with the ECU's calculated operating conditions.
P0102: Mass-air-flow circuit low input
The MAF sensor signal is lower than expected for the engine speed and load.
P0106: Manifold absolute pressure range / performance
The MAP sensor signal does not match the pressure expected from throttle position, boost, engine speed, and airflow.
P0130: Oxygen sensor circuit malfunction, bank 1 sensor 1
The upstream oxygen or lambda sensor signal is implausible, missing, or outside the control range expected by the ECU.
P0171: System too lean, bank 1
Fuel trim has reached a lean threshold because the ECU is adding more fuel than expected.
