The camshaft of the AI-4HK1X engine is the core component of the gas distribution mechanism, like the "nervous system" of the engine, which controls the rhythm of "breathing".

Common faults and diagnosis

Fault phenomenon: difficult to start or unable to start, insufficient power/poor acceleration, unstable idling/abnormal shaking, abnormal noise.

Common causes of failure:

1. Mechanical wear: cam surface, shaft neck wear or bending.
2. Sensor failure: Camshaft position sensor (CMP) failure or abnormal signal due to incorrect installation gap.
3. Time misalignment: improper installation or misalignment of the camshaft gear

Diagnosis method:

1. Read the fault code: Use the diagnostic instrument to read the fault code recorded by the ECU (such as camshaft phase error).
2. Visual and measurement: check the wear and use a thousand-point meter to measure the curvature.
3. Check the right time: Confirm whether the camshaft gear mark is aligned when the stop point on a cylinder.

Maintenance

1. Core inspection items: strictly check the time mark; check the wear of the axle neck and cam, measure the axial gap; confirm the sensor installation gap and the wiring harness connection.
2. Maintenance points: use high-quality engine oil and replace it regularly, and regularly check the wear of the camshaft and accessories.
