P0341 on Chevrolet
Camshaft Position Sensor Circuit Range/Performance (Bank 1)
P0341 on Chevrolet vehicles indicates camshaft position sensor circuit range/performance (bank 1). Au7o has documented this code across 2 Chevrolet models — most commonly on Cobalt, HHR. 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. Typical repair costs on Chevrolet range from $400 to $2,000, depending on the specific model and root cause.
Common Causes of P0341
- •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)
P0341 on Chevrolet by Model
Chevrolet Cobalt(1 issue)
- Ecotec Engine Timing Chain Stretch and Guide Wear2005-2010
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.
Chevrolet HHR(2 issues)
- Ecotec Timing Chain Tensioner Failure and Chain Stretch2006-2011
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.
- Ecotec Timing Chain Stretch / Tensioner Failure2006-2011
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.
