P0341 on Cadillac by model: symptoms, diagnosis and fix
The 3.6L LLT direct-injection V6 used in the 2008-2011 CTS (and the 2007 gen-1 3.6L LY7) is among the best-documented GM V6 failures: the primary and secondary timing chains elongate well before 100,000 miles, throwing off intake/exhaust cam correlation. Chain wear is strongly accelerated by extended oil-change intervals and low oil level, which starve the hydraulic chain tensioners. GM acknowledged the defect with Special Coverage bulletin 11340 (revisions A/B/C) extending timing-chain coverage to 10 years / 120,000 miles on affected models including the 2007-2009 CTS, and with service bulletin 12-06-01-009F describing the updated chain/tensioner/guide kit. This is an LLT/LY7 direct-injection-era issue and should not be attributed to the later LFX or to the 2.0L LTG four.
Common Symptoms
- Rattle or chirp from the front of the engine on cold start
- Check engine light with camshaft position correlation codes
- Rough idle and hesitation under load
- Reduced fuel economy
- Engine may crank but not start in advanced cases
How to Fix
Confirm with a scan tool that cam-correlation codes (P0008/P0009/P0016/P0017) are present and check for a rattle on cold start. The repair is the full updated GM timing-chain kit - all three chains, tensioners, guides, and usually the cam actuators - not just the stretched chain. Verify eligibility for GM Special Coverage 11340C (10yr/120k) at a Cadillac dealer before paying out of pocket; many owners had this done free. Afterward, run 5,000-mile oil changes with dexos-spec oil and check level monthly, since tensioner health depends entirely on oil condition.

Frequently asked questions
What does P0341 mean on a Cadillac?
P0341 stands for "Camshaft Position Sensor Circuit Range/Performance (Bank 1)." This code means the camshaft position sensor on Bank 1 is sending a signal that is present but doesn't make sense to the engine computer (a range/performance fault), often because it disagrees with the crankshaft position signal. The cam sensor tells the computer where the camshaft is so it can correctly time fuel injection and spark, and on engines with variable valve timing it also confirms cam phaser movement. When the signal is out of range, intermittent, or doesn't correlate properly, the computer flags this code, and you may notice hard starting, rough running, or reduced power. Causes are commonly a worn sensor, a stretched timing chain, or a problem with the cam phaser/tone ring. On Cadillac it is documented across 1 model: CTS.
What are the most common causes of P0341?
The most common causes of P0341 are: Failed or weak camshaft position sensor, Damaged or corroded sensor wiring/connector, Stretched or worn timing chain causing cam timing drift, Faulty variable valve timing (VVT) cam phaser or solenoid, Damaged camshaft reluctor (tone) ring, Low or dirty engine oil affecting VVT operation, Incorrect sensor air gap or installation, Faulty PCM/ECM (rare). The specific cause varies by vehicle.
How much does it cost to fix P0341 on a Cadillac?
Published repair estimates on Cadillac range from $1,800 to $3,500 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.
