P0016 on Opel
Crankshaft/Camshaft Position Correlation - Bank 1 Sensor A
P0016 on Opel vehicles indicates crankshaft/camshaft position correlation - bank 1 sensor a. Au7o has documented this code across 4 Opel models — most commonly on Astra, Corsa, Grandland. 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 Opel range from $700 to $4,500, 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 Opel by Model
Opel Astra(1 issue)
- 1.4 Turbo (A14NET) Timing Chain Stretch2009-2018
The A14NET 1.4 turbo engine in Astra J/K, Corsa D/E, Mokka A, and Adam can suffer timing chain stretch typically between 80,000-140,000 km. IMPORTANT DIAGNOSTIC DISTINCTION: brief (1-3 second) rattle ONLY on cold start is more often a worn dual-mass flywheel — see Vauxhall TSB E-14-3157 for 2010-2014 A14NET. Persistent rattle, misfire codes, or rattle that extends beyond cold start point to timing chain stretch. Chain skip causes valve-piston contact.
Opel Corsa(1 issue)
- Corsa D 1.2 / 1.4 Petrol Timing Chain Stretch2006-2014
Naturally-aspirated 1.2 (Z12XEP/A12XER) and 1.4 (Z14XEP/A14XER) engines in Corsa D (and Adam) suffer timing chain stretch — distinct from the A14NET turbo issue. The 1.4 87hp shows first symptoms as early as 60,000-80,000 km; the 1.2 typically at 80,000-100,000 km. Root cause is tensioner bleed-off overnight + chain wear, worsened by long oil intervals or low-grade oil. Cold-start rattle (1-30 seconds) is the classic early sign.
Opel Grandland(1 issue)
- Grandland X 1.6 THP Timing Chain Stretch2017-2021
The PSA/BMW "Prince" 1.6 THP engine in early Grandland X (2017-2021) suffers timing chain stretch, also documented across Peugeot 3008/5008 and Citroën C5 Aircross. Symptoms appear from 80,000 km. Same root cause as the well-documented MINI Cooper S timing chain issue from the same engine family.
Opel Vivaro(1 issue)
- Vivaro B 1.6 BiTurbo CDTI (R9M) Timing Chain Stretch2014-2019
The Renault-sourced R9M 1.6 BiTurbo CDTI used in Vivaro B (and Trafic III, Movano B) develops timing chain stretch, typically 100,000-180,000 km. Cold-start rattle, misfire codes, then potential chain skip causing valve damage. Particularly bad on stop-start fleet use without regular oil changes.

What does P0016 mean on Opel?▼
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 Opel specifically, this code is documented across 4 models.
What causes P0016 on Opel vehicles?▼
Common causes on Opel: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0016 on a Opel?▼
Repair costs on Opel range from $700 to $4,500, depending on the specific model and root cause.
