U0055 Opel Corsa D code definition:
U0055 is a kind of OBD-II Diagnostic U-Network Diagnostic Trouble Code for Opel Corsa D.
U0055 Opel Corsa D is defined as Knock Sensor Circuit Range Performance (Bank 1 or Single Sensor). This refers to camshaft timing, which in this case is over-retarded. Other symptoms that may indicate this problem are when the Check Engine Light illuminates and when there is a visible lack of engine power.
Symptoms
Symptoms of a U0055 Opel Corsa D diagnostic trouble code may include:
- Faulty or damaged wiring
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Poor fuel economy
- Rich or lean exhaust
|
Possible Causes :
- Faulty IMRC actuator relay (if equipped)
- A large air leak at or near the number one oxygen sensor would also cause a lean mixture.
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses
- Vehicle Speed Output Circuit Problem
- Cruise Control Servo Indicates Low Problem
- A/C System High Pressure High Temperature Problem
- PCM Stack Overrun Problem
- Transmission Control Module Reprogrammable Memory Problem
Repair Processes :
Use the DVOM to test resistance and continuity on all system circuits if actuator and sensor resistance levels are in compliance with manufacturer's specifications.
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
