P0016 on Pontiac by model: symptoms, diagnosis and fix
The 2.4L Ecotec LE5 in 2007-2010 G6 (and shared Cobalt SS, Malibu, HHR, Saturn Aura/Ion, Solstice) develops timing chain stretch — a very well-documented engineering issue across Ecotec forums and independent shops. Root cause: GM's original Oil Life Monitor allowed intervals up to 12,000 miles, starving the chain. Note: while GM issued Special Coverage Adjustment 11340C covering timing chain stretch on the 3.6L LFX/LLT V6, the 2.4L Ecotec did NOT receive the same blanket warranty extension. Some owners obtained goodwill repairs through dealer-level escalation.
Common Symptoms
- cold start rattle
- misfire
- check engine light
- reduced power
How to Fix
Full timing chain kit replacement (chain, tensioner, guides) ~$1,200-$2,000. If you experience the issue under 100,000 miles, request a goodwill-assistance review at a GM/Chevy dealer (not all approved, but some are). Use dexos1 full-synthetic 5W-30 and stick to 5,000-mile intervals going forward.

The turbocharged 2.0L Ecotec LNF (Solstice GXP) is prone to timing chain and balance-shaft chain stretch as the plastic guides and tensioner wear. A worn tensioner produces a cold-start rattle; if the chain skips timing on this interference engine it can bend valves or damage pistons. P0016/P0017 (crank/cam correlation) codes typically accompany a stretched chain.
Common Symptoms
- Cold-start rattle/clatter from the front of the engine
- Check engine light
- Rough idle
- Loss of power or no-start if timing jumps
How to Fix
Replace the complete timing chain kit along with the balance-shaft chain kit, guides, tensioner, and water pump together since the labor overlaps. Addressing chain noise promptly prevents catastrophic interference-engine damage.

Frequently asked questions
What does P0016 mean on a Pontiac?
P0016 stands for "Crankshaft/Camshaft Position Correlation - Bank 1 Sensor A." P0016 means the engine computer found that the crankshaft and camshaft position sensors on Bank 1 (Sensor A) are not lining up the way they should — the timing 'correlation' between them is out of range. These two sensors tell the computer where the pistons and valves are so it can time fuel injection and spark precisely. When their signals don't agree within tolerance, the computer sets this code. It generally indicates an engine timing issue, which may be a worn timing chain, a sticking variable valve timing component, or a sensor problem, and can cause rough running, hard starting, or potential engine damage if ignored. On Pontiac it is documented across 2 models: G6, Solstice.
What are the most common causes of P0016?
The most common causes of P0016 are: Stretched timing chain or worn timing components (guides/tensioner), Faulty camshaft position sensor or crankshaft position sensor, Stuck or faulty variable valve timing (VVT/VCT) actuator or solenoid, Low or dirty engine oil affecting the VVT actuator, Clogged oil control valve or restricted oil passages, Timing chain/belt installed one tooth off after service, Damaged reluctor/tone ring on the crankshaft or camshaft, Wiring or connector faults at the position sensors. The specific cause varies by vehicle.
How much does it cost to fix P0016 on a Pontiac?
Published repair estimates on Pontiac range from $800 to $2,500 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.
