P1387 Mazda Code - Camshaft Position Timing Solenoid 2 Circuit

P1387 indicates an issue with the Camshaft Position Timing Solenoid 2 Circuit, which controls the variable valve timing (VVT) system on your Mazda.

Symptoms may include reduced engine performance, poor fuel economy, rough idling, difficulty starting, or the Check Engine Light being illuminated.

Common causes include a faulty camshaft position timing solenoid, damaged wiring or connectors in the circuit, low engine oil level or pressure, or dirty oil affecting VVT operation.

Yes, low or dirty engine oil can restrict the operation of the camshaft timing solenoid, leading to the P1387 code.

Diagnosis involves checking the camshaft timing solenoid, inspecting wiring and connectors for damage, testing the oil pressure, and ensuring the engine oil is clean and at the correct level.

Driving with this code is not recommended, as it may cause poor engine performance or further damage to the VVT system.

Repair costs vary but typically range from $150 to $500, depending on whether the issue is with the solenoid, wiring, or other components.

Yes, a defective solenoid is a common cause of the P1387 code as it directly impacts the VVT system's operation.

Repairs may include replacing the camshaft timing solenoid, repairing damaged wiring, cleaning or replacing dirty oil, and ensuring the oil pressure is adequate.

In rare cases, a software update to the engine control module (ECM) may be required, but this is less common compared to mechanical or electrical repairs.
