i keep gettin this code so i replaced my front right O2 sensor and it's still there. my car does not feel or sound like it's misfiring help please.

 

p0308?....8? What year is your car?

 

95 se. just 0308 i did the ecu screw thing.

 

are the 2 white wires on the o2 sensors interchangable?? maybe that's my problem...

 

The white wires are interchangeable. With the engine warmed up, maintaining engine speed aroung 2000 rpms, you should get voltage between white wire and chassis ground which periodically changes from 0v->1v->0v so on. Minimum should be 0-0.3v, max: 0.6v-1v. Get the FSM for more details.

 

Did you reset the ecu?

 

yes i did.

 

so after a week of city driving i didn't have it and 2 mins on the hwy and my buddy cel light comes on witht he same code again

 

does any1 know where this module is or where the wires and plug(s) are located it only comes on when i'm on the hwy but driving in the city i'm fine.

0308
Diagnostic Trouble Code 0308 points to a problem with the Engine Control Module Closed Loop Logic for the Right Bank. The right cylinder bank is also called the rear bank. It is cylinders 1,3,5.

DTC 0308 is detected when the closed loop control function for the right bank does not operate even when the vehicle conditions meet the criteria (engine at normal operating temperature, etc.). Possible causes include ...
- Harness or connectors (The sensor circuit is open or shorted.)
- a defective Front Heated Oxygen Sensor sensing element.
- a defective Front Heated Oxygen Sensor heater.

 

Test the circuit

 

Yeah, test the circuit.

 

the O2 wiring u mean?
