My 1996 chrysler town & country keeps flashing the door ajar light, ringing the alert bell, and randomly locking and unlocking the doors whenever i step on the accelerator. It does it every few seconds and its driving me nuts. What could be causing this kind of problem and what do I do to fix it?
It also failed the smog test with more than double the allowable amounts for a gross polluter. The only OBDC code is P0140 which is "oxygen sensor ckt inactive (bank 1, sensor 2)". I replaced the sensor upstream of the catalytic converter but the code is still showing. Is that code for the sensor downstream of the catalytic converter? The smog test tech seems to think that it is more likely a bad catalytic converter rather than just the oxygen sensor because of the extremely high readings of pollutants. What do you think I should do?
For the door chime and locks your problem is a door jam switch or th bcm push and pull on the sliding door and see it would be a good idea to keep a 2nd key in your pocket
Door ajar - probably a defective or unplugged door switch. Try pulling them, one at a time and checking the wire connections on them.
