![]() If you’re not comfortable further diagnosing this issue at home, we recommend finding a RepairPal-certified shop to pinpoint the problem and give an accurate estimate for repairs. If the oil level is good and the sensors are all reading correctly, the issue is likely with the camshaft or the engine’s timing, which are repairs not suited for beginner DIYers. Using the live data function of the FIXD sensor and app allows you to read and analyze engine data to properly diagnose a P0012 code. ![]() With a P0012 code, the first step is to get it properly diagnosed to figure out what is causing the malfunction in the camshaft’s timing. ![]() Other codes such as misfire codes (P0300-P0308).Faulty intake valve timing control solenoid.Short in intake timing control/oil control circuit.The P0012 code is set when the ECM detects the camshaft timing for the intake camshaft on bank 1 is more retarded than what it has been set to be. The camshaft(s) is(are) adjusted by the ECM through the use of an oil control valve(s) (OCV) also called variable valve timing control solenoid valves. The variable valve timing system increases fuel economy and engine performance by regulating when the intake and exhaust valves are opened and closed. This DTC is triggered by a number of internal engine issues from dirty, low or sludged oil to incorrect camshaft timing. Diagnosis: It is important to complete the entire diagnostic process when diagnosing the P0012 code.Repair Urgency: Fix this code immediately (same day if possible) to avoid internal engine damage.Issue Severity: SEVERE – Stop driving immediately.P0012 definition: Intake Camshaft Position Timing- Over-Retarded (Bank 1).
