2001 Camaro P0341 Code: How to Test for Intermittent Sensor Connection Without a Scan Tool
I've read that you can wiggle the wires connected to the crankshaft position sensor (CPS) and if there's a loose or intermittent connection, the 'Check Engine' light may turn off. Is this accurate? I originally thought the fault code would only clear after being reset in the ECM, or perhaps I'm mistaken—does it require a scope or multimeter to detect actual voltage fluctuations when moving the wires?
You can use an oscilloscope to observe small intermittent variations in sensor voltage directly from the circuit. A multimeter can also help detect signal inconsistencies during wire movement. The P0341 code is stored in the ECM and typically clears when a stable, correct signal is detected during the next key cycle. For diagnosing intermittent issues, using either an oscilloscope or multimeter is recommended to verify sensor performance.
