P1347 – OBD-II DTC

OBD-II DTC P1347 – Crank / Cam Sensor Range / Performance

DTC P1347 meaning

DTC P1347 refers to a diagnostic trouble code that indicates a problem with the range or performance of the crankshaft and camshaft position sensors. These sensors are crucial for the engine’s timing and overall performance. When the Engine Control Module (ECM) detects that the signals from these sensors are out of the expected range or not performing as they should, it triggers this code.

Common symptoms associated with DTC P1347 may include:

• Check Engine Light illuminated
• Engine misfires or runs rough
• Decreased engine performance
• Difficulty starting the engine
• Unusual engine noises

DTC P1347 causes

Several factors can lead to the triggering of DTC P1347, including:

• Faulty crankshaft position sensor
• Faulty camshaft position sensor
• Wiring issues or poor connections in the sensor circuits
• Timing belt or chain problems
• Faulty Engine Control Module (ECM)

DTC P1347 seriousness

DTC P1347 can be serious as it affects the engine’s timing and performance. If left unaddressed, it may lead to further engine damage, reduced fuel efficiency, and increased emissions. It is advisable to diagnose and repair the issue promptly to avoid more significant problems.

How to diagnose DTC P1347

To diagnose DTC P1347, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the code.
