Hi,
I have had the MIL light come on on the dash, i have tested with an OBDII bluetooth adaptor and Torque app on my phone
It originally had the error TID$01 CID$05 constant voltage rich to lean fail
Max 64 current 186
(or something very similar)
tried some cat cleaner as the internet seems to have a lack of info on these codes for aygo's
current value went down to 146
I monitored the sensors before and after cat and it seemed that the after one was erratic, plus the cheapest to replace, so i opted to change it
Reset the error and car seemed quieter and more responsive
But running the tests again, it still showed current value of said parameter was 146
i tried thrashing it a bit and taking it up to high speeds to try burn anything off the cat, and it went up today to 151 !
anybody know what the TID$01 CID$05 actually refers to?
I have monitored the temperature sensor and warms up ok, and sits dead on 84C when diriving normally, so i'm guessing that is ok
by the way, in between it having a dash fault, it has passed an MOT on emissions, which suggests the sensors rather than the actual CAT
Or just toyota limits being very tight
Any help and or advice appreciated, before i start spending on more un-needed things
