Hi Im David, thanks for visiting the site. why did you replace all the timing components and sensors without troubleshooting what the exact problem is? your very first step should have been checking the condition and continuity of the wiring to the cam and crank sensors.

Expert:  david craig replied 1 month ago.

you need to do a continuity of the wiring to these sensors. also inspect the condition of the wires and connectors.

hello???????

Hello and welcome to JustAnswer!

This code sets when the PCM sees an issue with the cam or crank signal but is unable to determine which is incorrect. This can be either sensor, wiring and connections, or improper cam timing.

When did the code start setting as opposed to the parts being replaced?
