Can some please tell me if all 4 oxygen sensors are the same on my 2003 X-Type 3.0 V6. Or do they vary from one to the other?


Thanks

 

They are not the same. The two uppers match each other and the two lowers match each other, but the upper and lower sensors have different part numbers.

 

dabears, like Alfa said, the up stream sensors are one type of sensor and the downstream ones are a different sensor. Left to right they are the same. You will also find that they have different plugs on them as I recall. So, you can't mix up the up stream and down stream sensors as the plugs are side by side.

 

Ok I had the CEL checked I got 3 codes p1647
P0057 HO2S Heater control Circuit(Bank 2 Sensor 2)
P1000

I found a blown fuse F42 Will the fuse throw this code?

 

Semantics maybe, but the blown fuse doesn't throw the code - it's the circuit that the fuse is on that does. From what I've been able to dig out of wiring diagram in my Haynes manual, fuse F42 is 5 amp on circuit going to the inertia fuel cut-off switch. Five amp fuses are the lowest amperage I see on the diagram by the way. Does car run? It really helps if you provide more basic information on your car when posting - year/engine/transmission/miles. Add the basics to your signature in profile or provide them when you start a thread.

 

The OEM made a major wiring change in the 2004 models. The fuse locations and designations were changed for all 2004 cars after March 2004.
Fuse 42 prior to March 2004 is a 30 amp fuse for Oxygen sensor heater B. Fuse 38 prior to March 2004 is a 30 amp fuse for Oxygen sensor heater A.
Both fuses are in the engine compartment fuse box.

 

Ah ha. I'm new to this make, so that helps OP a bunch.
