P0024 on Chevrolet
Exhaust Camshaft Position Timing - Over-Advanced (Bank 2)
P0024 on Chevrolet vehicles indicates exhaust camshaft position timing - over-advanced (bank 2). Au7o has documented this code across 1 Chevrolet model — most commonly on Traverse. This code means the exhaust camshaft on Bank 2 is timed more advanced (earlier) than the computer commanded. The variable valve timing system uses an oil-pressure-driven cam phaser and a control solenoid to set camshaft position; the computer compares the commanded position to the actual measured position. When the exhaust cam on Bank 2 reads too far advanced, P0024 sets. Bank 2 is the side of the engine not containing cylinder number one. Symptoms can include rough idle, reduced power, and poor fuel economy. Typical repair costs on Chevrolet range from $150 to $900, depending on the specific model and root cause.
Common Causes of P0024
- •Stuck-open or clogged variable valve timing (oil control) solenoid
- •Low or dirty engine oil
- •Failed exhaust camshaft phaser/actuator (Bank 2)
- •Clogged oil control valve screen or oil passages
- •Stretched or worn timing chain
- •Wiring or connector fault at the VVT solenoid
- •Incorrect cam timing from prior service
- •Faulty PCM/ECM (rare)

- Camshaft Position Actuator Solenoid Faults on the 3.6L LFY — Over-Advanced Cam Timing and Rough Running2018-2020
The second-generation 3.6L LFY runs four cam phasers fed by oil-control solenoids. On early C1XX Traverse builds the solenoids stick or screen-clog with casting/machining debris and varnish, and the ECM calibration was itself part of the problem. The result is a set of correlated cam timing codes — commonly P0011 with P0014, P0021 and P0024 appearing together — plus a rough idle, a rattle on start-up as the phasers fail to lock, and reduced power. GM addressed the calibration side with bulletin N192266190 (ECM reprogram). This is distinct from the LLT/LFX timing chain stretch problem: the chains here are not necessarily worn, the phaser control is.

What does P0024 mean on Chevrolet?▼
P0024 stands for "Exhaust Camshaft Position Timing - Over-Advanced (Bank 2)." This code means the exhaust camshaft on Bank 2 is timed more advanced (earlier) than the computer commanded. The variable valve timing system uses an oil-pressure-driven cam phaser and a control solenoid to set camshaft position; the computer compares the commanded position to the actual measured position. When the exhaust cam on Bank 2 reads too far advanced, P0024 sets. Bank 2 is the side of the engine not containing cylinder number one. Symptoms can include rough idle, reduced power, and poor fuel economy. On Chevrolet specifically, this code is documented across 1 model.
