My sons '97 Mazdz 626 failed the emissions test. After getting the repair work done, we cannot get the drive cycles to reset on the OBD sensors, even after driving over 150 miles. The sensors are, the CAT and the two 02 sensors. Can you give me any advice on how to get these to reset so we can pass the emissions test?
Thankyou

Disconnect battery for couple minutes then drive car at 52-58 mph for one minute then pull over shut off. Restart repeat that should do it.if not will need to have drive cycle preformed at a shop using scan tool.
