mudkeith Posted March 4, 2014 Author Posted March 4, 2014 Pulled codes with a obd book got a hold of a solus going to try that.
lenore Posted March 4, 2014 Posted March 4, 2014 Did you use Bosch or Denso sensors....? Denso only.... also check your flex pipe to see if it is cracked.
mudkeith Posted March 7, 2014 Author Posted March 7, 2014 Same open circuit going to ohm the wires from the ecu to the 02 plug
lenore Posted March 7, 2014 Posted March 7, 2014 The two sensors I believe are wired in series on the heater side, so If one has a open heater, than both do.
mudkeith Posted March 15, 2014 Author Posted March 15, 2014 Ok ohmed all the wires from the sensor to the ecu and all is good. I think the dealer screwed the ecu when a new key was programmed? The ck eng lt came on after it was programmed.
mudkeith Posted March 15, 2014 Author Posted March 15, 2014 Thinking about getting a used ecu off ebay.
