Showing matches for "air suspension".
C1130: Chassis control or suspension pressure fault
A chassis or suspension control module has detected an implausible pressure, height, or control-state condition.
P0101: Mass-air-flow signal range / performance
Airflow reported by the MAF sensor does not agree with the ECU's calculated operating conditions.
P0113: Intake-air temperature sensor circuit high
The ECU sees an intake-air temperature signal that is higher voltage than expected, often interpreted as an unrealistically cold reading.
P0411: Secondary-air injection incorrect flow
The ECU does not see the expected oxygen-sensor response when the secondary-air system runs on cold start.
P1101: Intake airflow system performance
Measured intake airflow does not match the ECU model across the expected operating range.
P0102: Mass-air-flow circuit low input
The MAF sensor signal is lower than expected for the engine speed and load.
P0068: Throttle body airflow correlation
Throttle position, manifold pressure, and measured airflow do not agree with one another.
P2279: Intake air system leak
The ECU detects extra unmetered air entering the intake system.
P0106: Manifold absolute pressure range / performance
The MAP sensor signal does not match the pressure expected from throttle position, boost, engine speed, and airflow.
P0118: Engine coolant temperature sensor circuit high
The coolant-temperature signal is implausibly high voltage, often read by the ECU as extremely cold coolant.
P0128: Coolant thermostat below regulating temperature
The engine is taking too long to reach expected operating temperature or is running cooler than the ECU expects.
P0171: System too lean, bank 1
Fuel trim has reached a lean threshold because the ECU is adding more fuel than expected.
P0172: System too rich, bank 1
Fuel trim has reached a rich threshold because the ECU is removing more fuel than expected.
P0236: Turbo boost sensor range / performance
The charge-pressure signal is outside the expected range or disagrees with operating conditions.
P0300: Random / multiple-cylinder misfire
Misfires are occurring across more than one cylinder or without one consistent cylinder pattern.
P0301: Cylinder 1 misfire detected
The ECU detected repeated combustion misfires on cylinder 1.
P0303: Cylinder 3 misfire detected
The ECU detected repeated combustion misfires on cylinder 3.
P0305: Cylinder 5 misfire detected
The ECU detects repeated combustion failure specifically on cylinder 5.
P0401: Exhaust-gas recirculation flow insufficient
Measured or inferred EGR flow is lower than the controller expects.
P0402: Exhaust-gas recirculation flow excessive
The ECU detects more EGR flow than requested, often because the valve is not closing correctly.
P0480: Cooling fan control circuit 1
The ECU cannot control or verify the primary electric cooling-fan circuit.
P0507: Idle control system RPM higher than expected
Idle speed is higher than the ECU's target after it has reached the limit of normal control correction.
P0544: Exhaust-gas temperature sensor circuit, bank 1 sensor 1
The ECU sees an electrical fault in an exhaust-temperature sensor used to protect the turbo and emissions system.
P2181: Cooling system performance
The coolant temperature behavior is outside the expected warm-up or operating range.
P2263: Turbocharger boost-system performance
The complete turbocharging system is not producing or controlling boost as expected.
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.
