P0341 on Ford by model: symptoms, diagnosis and fix
The 5.4L 3-valve (3V) Triton V8 in 2004-2014 Ford Expedition is notorious for cam phaser failures and timing chain stretch, representing one of the most common and expensive repairs on these trucks. The VCT (Variable Camshaft Timing) system uses oil pressure to actuate the cam phasers - when phasers wear out or chains stretch, the engine sets multiple camshaft correlation codes and rattles on startup. The factory oil pump also wears out at similar intervals, compounding the problem. Running low on oil or using the wrong viscosity dramatically accelerates failure. Left unrepaired, a failed phaser can cause a chain to jump timing, resulting in bent valves and catastrophic engine damage. Repair typically requires complete timing system replacement including both cam phasers, all four timing chains, guides, and tensioners - a 12-16 hour job.
Common Symptoms
- Loud rattling/knocking from engine on cold start (top-end rattle)
- Check engine light with codes P0340, P0341, P0344, P0345, P0346, P0349 (cam sensor/phaser codes)
- Codes P0016, P0017, P0018, P0019 (camshaft-crankshaft timing correlation)
- Rough idle, especially when cold
- Engine surging at idle
- Loss of power and poor fuel economy
- Rattle that worsens on acceleration at low RPM
- Multiple misfire codes accompanying timing codes
How to Fix
Complete timing system overhaul: replace both VCT cam phasers, timing chains (primary and secondary), all chain guides, and tensioners as a complete kit. Motorcraft timing chain and phaser kit (TKIT-2004A-MGA or dealer equivalent) is recommended. Also replace the oil pump if over 80,000 miles - worn pump cannot supply adequate oil pressure for VCT system. Use 5W-20 full synthetic oil only. Change oil every 5,000 miles maximum. Labor: 12-16 hours on Expedition due to 4WD and engine mounts.

Frequently asked questions
What does P0341 mean on a Ford?
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 Ford it is documented across 1 model: Expedition.
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 Ford?
Published repair estimates on Ford range from $1,800 to $4,500 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.
