was drivin on the highway when my car started runnin on 3 cylinders, pulled over and saw the spark plug wire fell off, now i got 3 cel codes Electric load detector-high voltage output, )O2 sensor heater circuit Bank 1 Senor 1, O2 sensor heater circuit Bank 1 Senor 2. Also my speedo doesnt work and goes crazy ever since my wire fell off. Does this all mean my ecu is fried? any other things it could be? If it is the ecu how much is one for a d16y7?

 

anyone?

 

have you checked any of your fuses? It sounds like it is going to be one of the 7.5amp fuses under the dash.

 

reset the ecu.

 

IF your engine ground is bad and the ECUs ground is poor as well. And if the plug wire managed to backfed through the sensor grounds or shielding it could cook the ECU. But it's highly doubtful.

double check your engine grounds, reset the ECU, replace the plug wires and see what happens.

 

cleared the cel lights an as soon as the car starts they all come back, i know people who have fried there ecu ant they tell me i most likely did too, any ideas wat else it can be?

 

contrary to what most people think, its very hard to fry an ecu. i would look elsewhere first.

 

Finding somebody with a Y7 ecu shouldn't be hard. Try that.
