MOLTIVE COCKTAIL IT
Have you had your 4 oxygen sensors replaced? It turns out when they replaced my oxygen sensors, they were after market parts so the service engine light did not come and gave codes even though they were replaced.
Of course not. They are screwed into the exhaust system and can be easily replaced.
I had all sensors replaced in my 03 Trailblazer and the check engine light stiil comes on. Why?
There are dozens of reasons. But in most cars of this model some sensors just become old and have to be replaced. When sensors fail ECU sets off the check engine light.
No not a chance All mounts are WAY different not to mention the PCM and wiring and sensors
To fix an engine light code of 133 on a 1996 Ford Bronco with a 351 engine, the oxygen sensors need to be replaced. There are two oxygen sensors on this vehicle. One is on the driver's side and the other is on the passenger side of the exhaust or catalytic converter.
There are sensors all over the engine and transmission. There are also sensors at the wheel bearings and in the exhaust.There are sensors all over the engine and transmission. There are also sensors at the wheel bearings and in the exhaust.
I just replaced the ECM and the code went away. I was not able to read any of the sensors on the engine with the scan tool. Once the ECM was replaced, everything was OK>

It is probably your egr valve that needs replaced!
total power produced engine is called indicated power.
Catalist temp performance poor. Esentially the 02 sensors are reading poor cat performance. It could be the )2 sensors are old and tired but most often it means the Catalist needs to be replaced.
