Intermittent open circuits sound like an electrical problem to me, so my first course of action would be to follow the wiring and look for wear or breaks which could cause a short or loss of signal. I'd also pull the connector apart and check for corrosion on the contacts, cleaning them with ...

Other causes include a exhaust leak before the catalytic convertor, misfires, defective oxygen sensors,MAP and MAF sensors. Another possility could be ...

If I'm not mistaken, OBDII and CAN are two separate communication protocols on separate wires. OBDII uses serial (older and slow) communications on two wires.

Canbus was created as electronics ...
