P0024 on Nissan
Exhaust Camshaft Position Timing - Over-Advanced (Bank 2)
P0024 on Nissan vehicles indicates exhaust camshaft position timing - over-advanced (bank 2). Au7o has documented this code across 1 Nissan model — most commonly on Altima. 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 Nissan range from $1,000 to $2,500, 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)

- P0016 — Crank/Cam Position Correlation from Stretched Timing Chain & Worn Guides/Tensioner2007-2018
P0016 is one of the most well-documented Altima powertrain failures and is a hallmark of the 2.5L QR25DE (it also affects the 3.5L V6). The ECM sets P0016 when the camshaft (Bank 1, Sensor A) and crankshaft signals fall out of their expected relationship. On the Altima this is most often caused by a physically stretched timing chain combined with worn plastic timing-chain guide rails and a failing chain tensioner: as the chain slackens, cam timing drifts and the correlation code sets. A contributing root cause is sludge building up behind the primary drive gear, which starves the tensioner of oil pressure and lets the chain slap. The classic early warning is a rattle from the front of the engine on cold start that worsens over time. Related VVT/correlation codes (P0011/P0021/P0024) often accompany it. If ignored, a jumped chain can cause valve-to-piston contact and catastrophic engine damage.

What does P0024 mean on Nissan?▼
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 Nissan specifically, this code is documented across 1 model.
What causes P0024 on Nissan vehicles?▼
Common causes on Nissan: 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.
