P0009 on Cadillac
Engine Position System Performance - Bank 2
P0009 on Cadillac vehicles indicates engine position system performance - bank 2. Au7o has documented this code across 3 Cadillac models — most commonly on SRX, STS, XTS. This code means the engine control module detected that the position of the camshaft(s) on bank 2 is out of alignment with the crankshaft beyond an acceptable range. The computer compares crankshaft and camshaft position sensor signals to confirm the valve timing is correct; when bank 2 is off, the engine's intake and exhaust valves are not opening and closing at the proper moments. This can cause rough running, reduced power, hard starting, or rattling, and on engines with variable valve timing it often involves the timing components or the phasing system. It generally indicates a mechanical timing problem — such as a stretched chain or jumped timing — on the bank of cylinders not containing cylinder 1.
Common Causes of P0009
- •Stretched or worn timing chain on bank 2
- •Worn timing chain guides or tensioner
- •Faulty camshaft phaser / variable valve timing actuator
- •Stuck or clogged VVT oil control (cam phaser) solenoid
- •Low oil level or dirty oil affecting VVT operation
- •Camshaft or crankshaft position sensor fault
- •Timing chain that has jumped a tooth (skipped timing)
P0009 on Cadillac by Model
Cadillac SRX(1 issue)
- High-Feature V6 Timing-Chain DTCs Require Exact Kit Identification2010-2012
GM bulletin 12-06-01-009E covers listed 2010-2012 SRX High Feature V6 applications when worn timing chains set P0008, P0009 or P0016-P0019. It identifies application-specific service kits and warns that sprockets, actuators and guides should not be replaced automatically; guides are replaced only when wear reaches the base friction material.
Cadillac STS(1 issue)
- 3.6L V6 Timing-Chain DTCs Require Exact Kit and Guide Inspection2007-2011
GM bulletin 12-06-01-009E covers listed 2007-2011 STS 3.6L High Feature V6 applications when worn timing chains set P0008, P0009 or P0016-P0019. It identifies application-specific service kits and warns that sprockets, actuators and guides should not be replaced automatically; guides are replaced only when wear reaches the base friction material.
Cadillac XTS(1 issue)
- Multiple Cam/Crank Correlation DTCs Require Chain, Tensioner and Reluctor Diagnosis2013-2019
GM PIP3423P covers 2013-2019 XTS vehicles with the 3.6L LFX or LF3 engine when two or more of P0008, P0009 and P0016-P0019 are present. GM directs technicians to check for loose chains or tensioners and, if normal SI diagnosis does not find the cause, inspect whether the crankshaft-sensor reluctor moved. The bulletin does not establish automatic chain replacement.

What does P0009 mean on Cadillac?▼
P0009 stands for "Engine Position System Performance - Bank 2." This code means the engine control module detected that the position of the camshaft(s) on bank 2 is out of alignment with the crankshaft beyond an acceptable range. The computer compares crankshaft and camshaft position sensor signals to confirm the valve timing is correct; when bank 2 is off, the engine's intake and exhaust valves are not opening and closing at the proper moments. This can cause rough running, reduced power, hard starting, or rattling, and on engines with variable valve timing it often involves the timing components or the phasing system. It generally indicates a mechanical timing problem — such as a stretched chain or jumped timing — on the bank of cylinders not containing cylinder 1. On Cadillac specifically, this code is documented across 3 models.
What causes P0009 on Cadillac vehicles?▼
Common causes on Cadillac: Stretched or worn timing chain on bank 2, Worn timing chain guides or tensioner, Faulty camshaft phaser / variable valve timing actuator, Stuck or clogged VVT oil control (cam phaser) solenoid, Low oil level or dirty oil affecting VVT operation. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0009 on a Cadillac?▼
Repair costs vary widely depending on the root cause and specific Cadillac model.
Which Cadillac models have P0009 documented?▼
Au7o has documented P0009 on 3 Cadillac models: SRX, STS, XTS.
