Fits best here as a "repair" question.

Odd - crank position is the primary timing sensor, though you've still got a cam sensor. Crank sensor is usually considered vital for proper running (spark) and the two are used in concert for many of the ECU functions that check for proper operation.

 

Fix it, if you lose battery power and keep alive memory you may be stranded.

Crank sensor tells PCM when #1 cylinder at TDC and cam tells PCM which of two TDCs it can be. Used to set up spark timing and FI timing. You're running off past map now that PCM has defaulted to, it WILL catch up with you if you don't fix it.

 

Thanks for the knowledgeable advice.

Something must be intermittent either in the cable, connector or sensor, because when it was connected the engine sometimes ran very poorly until I repositioned the cable/connector. Now that the two wires have pulled out of the connector shell, there's no intermittent/inconsistent data and it runs just great.

Where's the camshaft sensor?

 

Look for them high on side of the cam tower molding in head. Probably on drivers end of the sticks.
