Q: How much does it cost to fix GMC P0011 error?

Costs vary depending on the root cause. Simple fixes like oil changes cost $50-100, VVT solenoid replacement runs $150-300, while camshaft actuator or timing chain repairs can cost $800-2000 including labor.

Q: What causes P0011 on GMC AFM engines?

Common causes include dirty or low engine oil, faulty VVT solenoid, clogged oil control valve screen, worn camshaft position actuator, or stretched timing chain. AFM engines are particularly sensitive to oil quality and maintenance intervals.

Q: Will P0011 cause my GMC to fail emissions testing?

Abstract

GMC error code P0011 indicates a problem with the intake camshaft position system performance on Bank 1, specifically with the Variable Valve Timing (VVT) actuator on Active Fuel Management (AFM) engines. This error means the camshaft timing is not responding correctly to the engine control module's commands, which can cause rough idling, reduced power, and poor fuel economy.
