This is bugging me - post 02 sensor

[Big_daddy]

for the past 2months trying to figure out whats wrong with my rear 02 sensor, can any one shed some light.

Keep getting the dam fault, "internal resistance too high" had it repalced twice now.

The main thing is, does the rear 02 sensor effect the air fuel ratio or its just there to check if the cats working.
My fuel consumption is abit high (V-power - £10 for 10 litres = 47miles) thats normal driving.

do u have a race/sports cat

Its a high flow cat, ive tried those spark plug spacers, like the one you have 4 slae .

They just change the fault to some thing else. Some thing about signal

but does the 02 sensor effect the fueling in any way, can this be mapped out? This is my main concern

Post cat sensor is only to test the cat is working and can be mapped out, Revo & APR stage 2 ignores it, I'm never sure about Custom Code, but I would've though it must do.

Whether or not going stage 2 would get around that code, I don't know. Could be a wiring issue?

Oh thats ok, was abit worried as it messing my fueling up, as it slighy running a tad rich as DPJ said on my power run graphs.

i would have thought the 1st sensor would deal with fueling
it can be mapped out yes

i have a decat on my LCR and i have the rear 02 sensor mapped out

If i do map it out, any types of fault i get with that sensor eg (internal ressitance too high), it wont trigger the engine light?

 

[ArosaRacer]

it should'nt do as its function is'nt used to measure anymore

right heres a dumb one i just put the spacers in mine and done the bloody front one will this be ok till i get time to change it?

 

[RikH]

you put the spacers in the front sensor moff?!!!!!!!!lol
it should be ok, id expect a code though

expect your fueling to be effected

 

[The MoffMeister]

i reckon it will but must say it doesnt stutter as much lol
