Happy New Year!

I pulled code p041 (No Cam Reference Signal from Ignition Control Module) while in diadnostic mode. Engine runs fine while driving, but at a stop the idle surges and sometimes engine will die. Do I need a new cam sensor?

It could be your camshaft position sensor or the ICM (ignition control module) or even a short somewhere in between. If you have a multimeter, you could do some testing.

Your sensors resistance should be 800-1200 ohms. If it is greater, check for an open. If it is lower, check for a short.

You can disconnect the CPS from the ICM and measure the voltage across the terminals of the connector while the engine is being cranked over. If you get 0.2V or less, the sensor needs to be replaced.
