P0341 on Chevrolet by model: symptoms, diagnosis and fix
The 2.2L and 2.4L Ecotec engines in the HHR suffer from timing chain tensioner failure and chain stretch, particularly on early production years. The timing chain tensioner does not receive sufficient oil at idle due to a design fault in early engines, causing accelerated wear. The 2.4L Ecotec is especially prone to this issue and also suffers from oil consumption problems. GM released revised tensioners and oil nozzles but many HHRs were never updated. Symptoms typically appear between 80,000-120,000 miles.
Common Symptoms
- Rattling noise on cold start that may diminish when warm
- Check engine light with P0017 camshaft position code
- Engine running rough or misfiring
- Reduced engine power under acceleration
- Timing chain noise that progressively worsens
How to Fix
Replace timing chain, tensioner (use revised GM part), guides, and sprockets as a complete kit. Do the water pump at the same time since it shares access. For the 2.4L, also address any oil consumption by checking the piston rings. Total repair cost is $800-$2,000 depending on engine and additional work needed.
Sources for this issue (1)
The 2.2L (L61/LE5) and 2.4L Ecotec four-cylinders are prone to timing chain wear caused by failing plastic guides and weak tensioners, often aggravated by extended oil-change intervals or low oil. Because the engine is an interference design, a stretched chain that jumps time can let pistons strike valves and destroy the engine. The telltale sign is a rattling or scraping noise from the passenger side of the engine, especially on cold start, frequently accompanied by code P0008/P0017 for cam-to-crank correlation.
Common Symptoms
- Rattling or scraping noise from passenger side of engine on cold start
- Check engine light with cam/crank correlation codes
- Rough running or misfire
- Engine may not start if chain has jumped time
- Reduced power
How to Fix
Replace the complete timing kit (chain, guides, tensioner and sprockets), not just one part, using quality kits (Cloyes, Melling, INA). Address any oil-consumption issue and use full synthetic oil with shorter change intervals to prevent recurrence.
Sources for this issue (1)
The 2.2L and 2.0L Ecotec engines in the Cobalt develop timing chain stretch and timing chain guide deterioration. The plastic timing chain guides wear over time, causing the chain to become slack and noisy. If left unaddressed, the timing chain can skip teeth, causing valve timing misalignment and potential engine damage. The issue typically develops between 80,000-150,000 miles. The water pump is driven by the timing chain on these engines, so both should be addressed together.
Common Symptoms
- Rattling or slapping noise on cold start
- Chain noise that worsens over time
- Check engine light with timing-related codes
- Rough idle or hesitation on acceleration
- Reduced engine power if timing has jumped
How to Fix
Replace the timing chain, tensioner, guides, and water pump as a kit when chain noise develops. DIY timing chain kit with water pump runs $200-$400 for parts. Labor at a shop runs $600-$1,200 due to the front-of-engine teardown required. Do not ignore chain rattle on cold start - it will worsen and can cause catastrophic engine damage.

Frequently asked questions
What does P0341 mean on a Chevrolet?
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 Chevrolet it is documented across 2 models: HHR, Cobalt.
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 Chevrolet?
Published repair estimates on Chevrolet range from $400 to $2,000 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.
