Chevrolet Cruze engine slight shake when accelerating

A mileage of about sixty five,000 km, outfitted using a handbook transmission 2010 models of Chevrolet Cruze 1.6L sedan. launch x431Reflects the owner: The car would be the car accident, the repair store replaced the cylinder head as well as oil pump just after engine failure lights, and there is a slight jitter.

Failure Investigation: Since the car is fault car, the very first use to discover, hear, touch, test a mix of solutions, preliminary screening with the auto. Opened the hood and located no important leakage, digital accessibility and breakage phenomena. Then commence the motor and located fault lights to the instrument, plus the gas doorway which has a slight shake of the phenomenon. Symptom in truth, as the operator, as reflected. ECM module with GDS detection P0016 (crankshaft position an consumption camshaft posture is unreasonable) obd2fault code. Examine the fault code, the very first response isn't on great timing, check the timing marks akin to the traditional situation. Measuring two camshaft situation sensor and two camshaft posture actuator solenoid valve line is typical. Attempted changed with the same kind of cars to the two camshaft posture sensor, two camshaft position actuator solenoid valve, two camshaft position actuators, two camshaft, crankshaft placement sensor, ECM module, motor wiring harness, though the fault persists.

The motor vehicle check, uncovered fault having a standing for a sizzling auto after starting up (P0016), re-check the engine timing situation is regular. With GDS comparing the data, read the motor idling: Determine 1 displays the truck diagnostic toolbreakdown car or truck, the consumption camshaft place command is 80%; Determine two exhibits the normal auto, the ingestion camshaft posture command is 62%.

In order to further more evaluation to determine the cause of the malfunction, chose to use the oscilloscope were calculated: the ingestion camshaft signal, the sign exhaust camshaft, crankshaft sign waveform. The waveform comparison using the normal auto and found the intake camshaft situation biased.
