Diagnostic trouble code P0341 code error stands for “Camshaft Position Sensor “A” Circuit Range/Performance (Bank 1 or Single Sensor).” it’s triggered when the powertrain control module (PCM) detects a drag with the signal being sent by the camshaft position sensor. It’s essential to notice that this code won’t be set unless the cam sensor signal disappears.
This code refers to drag with the camshaft position sensor (CMP) signal on Bank 1. It might be that the signal coming from the CMP isn’t matching, not within the expected range, or not appropriately timed with the crankshaft position sensor’s (CKP) signal. You furthermore may need to note that this code is often set by extended cranking periods.
Camshaft Position Sensor Circuit Range And Performance
Here is what P0341 means, in simple terms… Trouble code P0341 means the powertrain control module (PCM) detected a drag with the signal coming from the camshaft sensor. The camshaft position sensor (CPS) sends a wave signal (5 volts) to the PCM for each Top dead center (TDC) position of the compression stroke, also as pulse waves indicating the role of the cam sensor.
Signals are generated through a reluctor wheel attached to the camshaft. Specific points of the reluctor wheel travel by the camshaft sensor, the sensor regulates 5-volt reference voltage during a wave pattern. Anytime the camshaft sensor signal doesn’t correspond to the signals received from the crankshaft sensor, the PCM sets a trouble code P0341.
What Causes Vehicle To Trigger P0341 Trouble Code?
The PCM monitors the voltage from the camshaft sensor, and if it detects an incorrect voltage or irregular wave pattern, it’ll set an OBD-II trouble P0341 code error. Trouble code may indicate that one or more of the subsequent has occurred:
- Defective wiring and connector camshaft sensor
- Insufficient wiring connection at PCM camshaft sensor input
- Defective camshaft sensor
- Damaged camshaft reluctor wheel
- Spark system interference (uncommon on later model vehicles)
What Are The Symptoms Of Trouble Code P0341?
A P0341 trouble code will generally trigger the check engine light on. Counting on your vehicle’s make, the check engine light could also be mentioned because of the CEL, the Malfunction pilot light (MIL), or Service Engine Soon (SES) light. Freeze frame data containing information regarding engine sensor values when the ECM detected the P0341 fault will also be stored within the PCM’s ROM memory and may be accessed via an OBD-II scan tool.
Freeze frame data are going to be helpful to a technician when diagnosing the basis explanation for a P0341 trouble code when the fault isn’t easy to seek out. Possible symptoms include:
- MIL (Malfunction Indicator Lamp) or Check Engine light illumination
- Engine stalls during stop and doesn’t idle appropriately unless the accelerator is depressed
- Engine stalls when letting off the accelerator
- The engine may idle too high
- The engine may idle too low
- Poor fuel economy
- Possible no start condition
How to Diagnose the P0341 Code?
Diagnosis is crucial in addressing the error code. You would like to work out the precise explanation for the difficulty to work out the proper thanks to resolving it, which may be tricky, especially if you’re not an automotive professional.
If you’re confident of your DIY car repair skill, you’ll investigate the difficulty code to spot its root cause. Watch this helpful video regard to know-how to fix the po341 Code error.
Camshaft Position Sensor Location:
Some camshaft sensors are located within the distributor as Hall Effect or Optical units, but most cam sensors read directly from the camshaft itself, either employing a Variable Reluctance Sensor (sine waveform) or a Hall Effect (square wave) sensor. Variable Reluctance (VRS) Sensors typically have one, two, or three “teeth” on the camshaft or cam gear spinning past their tips. Hall Effect sensors will usually read slots cut during a cup-shaped wheel that spins very near the sensor.
Mechanics use an oscilloscope to record camshaft and crankshaft waveforms together and compare those to available suitable waveforms to work out if an engine is out of your time or the Variable Valve Timing (VVT) system is functioning correctly.
How To Fix P0341 Code Error?
Often replacing the camshaft sensor fixes trouble code P0341. However, it’s essential to see the subsequent first:
- Inspect the wiring at the camshaft sensor for melting or marks of corrosion
- the camshaft sensor for damage
- Inspect the camshaft reluctor wheel for missing or damaged teeth.
- You’ll get to remove the timing chain cover to examine the reluctor wheel if it’s not visible by removing the camshaft sensor
Even though many OBD-II trouble codes share symptoms and causes, there are no universal thanks to resolving them. If you’re not confident with your automotive know-how and DIY skills, don’t plan to fix the P0341 code. Let an automotive expert handle the difficulty to avoid exacerbating it accidentally.
Can I drive my vehicle with a P0341 trouble code and illuminated CEL?
Trouble code P0341 should be diagnosed and repaired as soon as possible and not recommended. However, you’ll drive your vehicle while trouble code P0341 is present unless the engine stall or stumbling is severe enough to hinder proper vehicle operation. Erratic engine speed could also be noticed.
Finally, don’t forget to consult your owner’s manual before attempting to resolve the P0341 code error. Repair instructions may vary supported your vehicle’s make and model.
