I brought this truck in for inspection and failed due to the o2 sensors. I have replaced both sensors and now the vehicle is running very rough.

After replacing both malfunctioning sensors I drove it and noticed the the vehicle will not take fuel. I drove it back to the auto store and the computer still shows that both of the sensors are bad. I have no idea what to do next the DTC:p0135 o2 sensor heater circuit malfunction bank one sensor one. DTC: p0141 o2 sensor heater circuit malfunction bank one sensor two. DTC: p0138 o2 circuit high voltage bank one sensor two.

i would have the convertors tested at a exhaust shop for backpressure.if the exhaust is not flowing correctly the o2 sensors will sense a prob since there is no code for backpressure or restricted exhaust the computer thinks the 02 sensors are failing.


you will get the same codes if you need a major tune up
