If I'm gonna check the driver's side connector....I'm gonna do the pass side also.

Tom,

I had a similar problem. Cleaned both sensors, cleared the codes worked for about 6 months. Then the code came back for passenger side. pulled the plug apart in the passenger foot well, cleared the code and has been working since.

Someone told me not to use dielectric grease on the bolts and connectors, it could cause an open in the circuit.

Clearing the codes is a PITA

Thanks John for your thoughts. I did the proceedure described over at the netreg site about correcting the frame grounding issue as soon as I got my Z.

I redid the driver's side sensor as my DIC is giving me a code 16, but there was no corrosion to interfere with the frame ground. I figured the next thing was to ohm out the sensor as per the FSM proceedure but I was caught off gaurd by the admonishments in the FSM about using a VOM. The FSM says to use this K-M tool kit for testing on the SIR system.

The warnings gave me pause to think about what I was doing. I reasoned that I can't see what could go wrong if I used my VOM to ohm out the sensor only and not any other part of the system.

Hopefully today I will have time to ohm the sensor to see if it is the cause of the code 16. I can't find any corrosion at any of the connectors' terminals and on the frame....I'm hoping I can isolate the trouble with my VOM and not set off the bag or harm any of the other parts in the system....I just can't figure what could go wrong if I ohm out just the sensor and not any other part of the system.

Tom,

I disconnected my battery for about 1/2 hour then disconnected the yellow sensor lead from the sensor inside at the passenger footwell. Then used the procedure to test the resistance, used an ohm meter on the sensor. It checked out OK. Cleaned up the pins on the connector and put it back together, Cleared the code and (knock on wood) has worked since. The lock that holds the connector together or the connector itself might have loosened up, at least on my car.

Best Regards, John
