- Oil flow restriction in the oil passages or the VCT valve body
- VCT solenoid stuck in position
- 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

P0018 MAZDA Description
The powertrain control module (PCM) monitors the variable camshaft timing (VCT) position for a misalignment between the camshaft and crankshaft. The test fails when the misalignment is 1 tooth or greater. This DTC can also be set due to VCT system concerns (oil contamination or VCT solenoid stuck).
