QuestionQUESTION: Replaced BOTH bank 1 & 2 Pre cat sensors and still have this error???!! And yes, the *&&% MIL Light! Any help on voltage checks or were to go from here?? Replaced ECU unit, and I still get this error on BOITH ECU's. Would you have the pinout diagram for the ECU?

ANSWER: Well perhaps it is the post-cat sensors that are giving the error. Also I would carefully check the wires to the sensors, as the code indicates an open circuit in the heater circuit. Let me know what you find, Jan

QUESTION: ok Found a cut wire on bamk 2 sensor 1 YES! And no light!! BUT ..... The E-Check says ... even though I still don't have a light on, their system won't communicate??? It shows a Catalyst monitor incomplete???!!! I get the same on my hand held Scanner ... Now what???
AnswerThe communication issue is a different one. If you are sure all the wires to the O2 sensors are now OK, can you read other aspects of the ECU OK? If you rectified the problem by re-attacing the wire, you did this with the ignition off? If it is just the catalytic monitor, I would check the wires with an Ohm meter, if OK disconnect the battery from the vehicle for about 10 minutes and try again. Also check all the fuses. Let me know, Jan
