Yeah, I searched, but one site that lists OBDII codes says something and then another sight will say something different.


Which o2 sensor is the P0176 code for? (Discovery 2)


Also, anyone have an accurate OBDII list for the Disco2? Or a link to a site that has one for these codes?

 

The ones I saw link that code to some sort of test for contaminated grade of "flex fuel" - ethanol content. So maybe your reader is making an educated guess? Any way to try at another auto parts store to see if they get same code (different brand of reader)? In the RAVE workshop manual under engine management there are tables of codes, but not all on one page. One on line is Land Rover OBD-II Trouble Codes

 

Fuel Composition Sensor Circuit Malfunction?

 

That is the correct issue for a 176, never seen it show up before and have no idea where to go with it other the hit the Rave for that sensor and code and find the testing procedure.

By the way, when are you heading out our way, the snow is starting to get pretty deep higher up on the good trails, might want to bring some chains.

 

I suspect that 0176 is a "universal" rather than specific to Rover code. Searched 1529 pages of D2 shop manual for p0176, nothing. In Fords it refers to the flex fuel sensor, which evaluates the alcohool content of the fuel.

From a Ford site:

Flexible Fuel Vehicles can run on fuel ethanol or on unleaded gasoline. The flex fuel sensor detects the alcohol content of the fuel to determine what type of fuel is being used. The FFV fuel system components are made from special materials to withstand the ethanol fuel.

Can't imagine that we have too much alcohol in the gas tank, but in the driver is another issue....

 

You are correct. All P0 codes (for any brand, not just Rover) are universal codes, and should mean basically the same thing on any vehicle. The P1 codes are manufacturer specific.

 

So a stock D2 would not have a flex fuel quality sensor and should not generate such a code? Does that suggest a whako code reader, or garbled data communication between ECM and other modules in the D2 (in other words, if it is really not a P0176, what is it)? Somthing made it go off, unless he just got within wifi range of the dealership and they "planted it"?

 

The 176 is on my list of Rover fault codes but I am unable to find anything relating to it in the Rave.
