Camshaft Position ‘A’ Timing Over-Retarded Bank 2
Table of contents
P0022 MERCURY Possible Causes
- Variable Camshaft Timing solenoid stuck open
- Continuous oil flow to the Variable Camshaft Timing (VCT) piston chamber
- Erratic camshaft position due to low oil pressure
- Oil flow restriction in the oil passages or the VCT valve body
- Faulty Variable Camshaft Timing
- Variable Camshaft Timing harness is open or shorted
- Variable Camshaft Timing circuit poor electrical connection
- Damaged camshaft position (CMP) sensor
- Open or short in the CMP sensor circuits
- Radio frequency interference (RFI) interference
How do I fix code P0022 MERCURY?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- Dirty oil can clog the small holes in the VCT valve. Start by replacing your oil (with the recommended oil weight) and oil filter, if you have not replaced in the recommended oil change interval.
Cost of diagnosing the P0022 MERCURY code
The cost of diagnosing the P0022 MERCURY code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of power
- Engine rough idle
P0022 MERCURY Description
The Powertrain Control Module (PCM) monitors the Variable Camshaft Timing (VCT) position for an over-advanced camshaft timing. The Diagnostic Trouble Code (DTC) will set when the camshaft timing exceeds a maximum calibrated value or remains in an retarded position.
