hey guys...i followed the instructions on pulling the code from the ecu. this is what i got 5 long pulses, 10 short pulses. im almost positive this is it b/c i double and triple checked. the decoder on vbxmaxima says that it's an invalid code. any suggestions?? im gonna check the code later this afternoon again just to make sure.

thanks

maybe you got it backwards and mean 10 long 5 short which is EGRC Solenoid valve

 

u might be right gtr. im gonna have to go back outside and take a look after i get out of class. thanks for the reply.

Diagnostic Trouble Code 0510 points to a problem with the Rear Heated Oxygen Sensor. This sensor is mounted in the exhaust stream, just downstream of the Catalytic Converter. When the two Front Heated Oxygen Sensors are operating properly the Rear Heated Oxygen Sensor is not used for engine control operation. It is used to monitor the condition of the Catalytic Converter. If either or both Front Sensors fail the Engine Control Module uses the signal from the Rear Sensor to maintain a correct fuel/air mixture.

DTC 0510 is detected when the signal from the Rear Heated Oxygen Sensor does not reach the expected maximum voltage threshold value. The possible causes include ...
- Harness or connectors (the sensor circuit is open or shorted.)
- Rear Heated Oxygen Sensor
- Fuel pressure
- Fuel injectors
- Intake air leaks

 

thanks so much daniel. i said this before, but i think the fact that i have a bad catalytic converter has something to do with this. a new one is being shipped to me and should be here by Thursday according to UPS, so hopefully by this weekend i'll have a new cat. one more question though, once i put this new catalytic converter on, and assuming it fixes the error, will the service engine soon light go off or do i still have to manually turn it off??

thanks

It will go off by itself ... eventually ... but I suggest you reset it manually. It's easy enough.
