P0016 on Pontiac
Crankshaft/Camshaft Position Correlation - Bank 1 Sensor A
P0016 on Pontiac vehicles indicates crankshaft/camshaft position correlation - bank 1 sensor a. Au7o has documented this code across 2 Pontiac models — most commonly on G6, Solstice. 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. Typical repair costs on Pontiac range from $800 to $2,500, depending on the specific model and root cause.
Common Causes of P0016
- •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
P0016 on Pontiac by Model
Pontiac G6(1 issue)
- G6 2.4L Ecotec (LE5/LAT) Timing Chain Stretch2007-2010
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.
Pontiac Solstice(1 issue)
- Timing chain and balance shaft chain stretch on the GXP 2.0T (LNF)2007-2009
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.

What does P0016 mean on 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 specifically, this code is documented across 2 models.
What causes P0016 on Pontiac vehicles?▼
Common causes on Pontiac: 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.
