P0344 on Jeep
Camshaft Position Sensor 'A' Circuit Intermittent (Bank 1 or Single Sensor)
P0344 on Jeep vehicles indicates camshaft position sensor 'a' circuit intermittent (bank 1 or single sensor). Au7o has documented this code across 1 Jeep model — most commonly on Wrangler. P0344 is a generic OBD-II code indicating the engine computer detected an intermittent or erratic signal from the camshaft position sensor 'A' on bank 1 (or the single sensor on inline engines). This sensor reports the camshaft's position so the computer can correctly time fuel injection and ignition. An intermittent signal means the data is dropping out momentarily, which can cause hard starting, stalling, hesitation, or rough running. It often points to a wiring or connection problem rather than an outright sensor failure. Typical repair costs on Jeep range from $350 to $2,500, depending on the specific model and root cause.
Common Causes of P0344
- •Loose, corroded, or chafed camshaft sensor wiring/connector
- •Failing camshaft position sensor
- •Intermittent open or short in the circuit
- •Damaged or contaminated reluctor/tone ring
- •Excessive air gap or debris at the sensor tip
- •Poor ground or unstable power supply
- •Worn timing components affecting sensor signal

- OPDA/Camshaft Synchronizer Failure Causing Squeal and Cam Gear Wear2005-2006
Late-TJ 4.0L Wranglers are well known for Oil Pump Drive Assembly (OPDA) failures, often described by owners as the 'screaming monkey' chirp or squeal from the engine bay. The OPDA can bind or wear internally, which may damage the camshaft gear and affect oil pump drive timing. If ignored, the issue can escalate from noise and check-engine lights to expensive internal engine repair.
