The P0341 diagnostic trouble code indicates a problem with the camshaft position sensor “A” signal on Bank 1 or a single-sensor engine. It is triggered when the PCM detects that the camshaft position signal is out of range, improperly timed, or inconsistent with expected values.
P0341 stands for “Camshaft Position Sensor ‘A’ Circuit Range/Performance (Bank 1 or Single Sensor).” The code is set when the PCM detects that the camshaft position sensor signal is missing, out of range, or not properly synchronized with the crankshaft position sensor signal.
This code will not be triggered unless the camshaft sensor signal goes away or deviates significantly from expected values. It can also be set during extended cranking periods.
The “A” designation typically refers to the intake camshaft. On V-type engines, it usually indicates the intake camshaft on Bank 1. Bank 1 refers to the side of the engine that contains cylinder number one.
On some Honda vehicles, the camshaft position sensor A monitors intake camshaft timing and sends pulsing signals to the PCM. The PCM compares these signals with the crankshaft position sensor to determine camshaft advance or retard.
If the pulse deviates from the expected range over a specific time period while the variable valve timing control (VTC) is not active, the PCM stores the P0341 code.
Example causes on a 2014 Honda CR-V LX 2.4L include:
Drivers may experience one or more of the following symptoms when P0341 is present:
Possible causes of the P0341 code include:
The severity of P0341 depends on the underlying cause. In some vehicles, the only noticeable issue may be an illuminated Check Engine light. In others, the engine may experience hard starting, stalling, or rough operation.
Ignoring the problem can lead to worsening drivability issues and unreliable engine performance, especially if timing-related components are involved.
Accurate diagnosis is critical to resolving the P0341 code. Use the following step-by-step approach if you have sufficient DIY experience:
Professional technicians may use an oscilloscope to compare camshaft and crankshaft waveforms against known good patterns to identify signal or timing faults.
There is no universal repair for P0341. The correct fix depends on the confirmed cause.
Some cam sensors are adjustable, such as those used in distributor-style or cam synchronizer applications. These require special tools and procedures and should not be adjusted by guessing. Non-adjustable sensors that mount directly to the valve cover or cam housing are typically plug-and-play replacements.
V-type engines often have a camshaft sensor on each bank. On some vehicles, a single failed sensor can cause hard starting.
If you are not confident in your repair skills, it is recommended to have a qualified technician perform the diagnosis and repair.
To complete a full four-stroke cycle, the crankshaft rotates twice (720 degrees). The camshaft controls valve operation and must stay synchronized with crankshaft movement.
The PCM uses both camshaft and crankshaft position sensor signals to determine:
By comparing real-time signals with stored reference patterns, the PCM can detect timing irregularities and set diagnostic codes when abnormalities occur.
The camshaft position sensor location varies by vehicle make, model, and engine design. Common mounting points include:
For example, on a 2017 Chevy Malibu, the sensors are located under the engine cover and valve cover area, with one sensor mounted on top and another near the rear of the engine on the driver’s side.
Some older or specialized designs integrate cam sensors into distributors using Hall Effect or optical sensors. Most modern systems use Variable Reluctance or Hall Effect sensors mounted directly near the camshaft.
The PCM uses crankshaft position data to track engine speed and position and camshaft position data to identify which cylinder is firing.
This information allows the PCM to:
If the camshaft sensor signal becomes erratic or drops out, the PCM sets fault codes such as P0341.
P0341 means the PCM detected a camshaft position sensor “A” signal that is out of range or not performing as expected on Bank 1 or a single-sensor engine.
Yes. In some cases, the engine may crank normally but fail to start if the PCM cannot properly determine camshaft position.
No. While both relate to camshaft position sensor issues, P0341 focuses on signal range and performance, while P0340 typically indicates a circuit malfunction.
Yes. Extended cranking periods can cause the PCM to detect abnormal camshaft signal behavior and set this code.
No. Some vehicles may only display the Check Engine light without noticeable drivability issues.
No. Bank 1 refers to the side of the engine that contains cylinder number one and only applies to V-type and boxer engines.
Yes. A stretched timing chain or failed tensioner can affect camshaft timing and trigger this code, often along with other related faults.
Some sensors are simple bolt-on replacements. Adjustable sensors require special tools and procedures and are better handled by experienced technicians.
No. Clearing the code without fixing the underlying issue will usually result in the code returning.
