P0021 on Dodge by model: symptoms, diagnosis and fix
The MultiAir variable valve timing solenoids fail causing check engine light with VVT codes, rough idle, loss of power, and poor fuel economy. Individual solenoids not available separately from Mopar - entire MultiAir assembly must be replaced.
Common Symptoms
- Check engine light with variable valve timing codes
- Rough idle
- Loss of power
- Poor fuel economy
- Valve tick noise
How to Fix
Replace entire MultiAir assembly (individual solenoids not sold separately by Mopar). Labor-intensive as it requires valve cover removal and special tooling.

Frequently asked questions
What does P0021 mean on a Dodge?
P0021 stands for "Intake Camshaft Position Timing - Over-Advanced or System Performance (Bank 2)." P0021 means the engine computer detected that the intake camshaft on bank 2 is timed too far advanced and won't return to its commanded position. Most modern engines use variable valve timing (VVT), where an oil-pressure-driven actuator rotates the camshaft to optimize power and efficiency; the PCM compares the camshaft's actual position to its target. When the cam stays over-advanced beyond an acceptable limit, this code sets. Bank 2 refers to the side of the engine that does not contain cylinder number one. You may notice rough idle, reduced performance, or lower fuel economy. On Dodge it is documented across 1 model: Dart.
What are the most common causes of P0021?
The most common causes of P0021 are: Dirty or low engine oil restricting the VVT system, Stuck or failed camshaft oil control valve (VVT solenoid) on bank 2, Clogged VVT solenoid screen or oil passage, Faulty camshaft position actuator / phaser, Wiring or connector fault at the VVT solenoid, Camshaft or crankshaft position sensor problems, Worn timing chain, guides, or stretched chain altering cam timing. The specific cause varies by vehicle.
How much does it cost to fix P0021 on a Dodge?
Published repair estimates on Dodge range from $1,000 to $2,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
