Heated Oyxgen Senson Control Module

[londonxk8]

hello - so - my car came up with the engine light error, so went to a jaguar indie in north london and he hookedi tup to a autel reader. when i went to the garage - i had the ABS light on, and the engine light. for the engine light, it came up with the code P1646 - heated oxygen sensor control module, bank 1 open/shorted. any advice on where i can get the part? my neighbor is an ex mechanic so i think he could install it if i could give him some guidance on where to locate the sensor.

so questions:

1. where can i buy the part or part number for this code? i have searcehd but there are downstream/upstream sensors - how do i know which one this?

2. any advice on a decent reader for the xk8. obII? my neighbor could then help with a lot of the faults!

for the ABS light - strangely after clearing the ABS code, it came back on again. but a few days later the ABS went off and the light has not come back on again. so beginning to wonder if these are just electrical issues.

any help appreciated!

Hi

the fault code will tell you which one to replace

P1646 is not listed on my list

you need to get it plugged in on IDS/SDD software, jaguar diagnostic software

same with the abs fault, get it plugged in on IDS/SDD and it will tell you exactly where the fault is, usually a wheel sensor

also if its a sensor on the abs, this can give you a engine management fault like limp mode, because it uses these for transmission and engine

cheers

hello joe - for the oxygen sensor error code - i did take a picture of the fault code from the reader.

it says:  P1646 - heated oxygen sensor control module, bank 1 open/shorted. 

do you know which one is bank 1? also, for the replacement part - i found these on europarts (is it the right part?). otherwise loads of other cheaper ones on eBay but just not sure which part to get

finally- another member recommend the icarsoft scanner. would that be a decent one to buy? i would like to save myself paying £40 for code reads from my indie and the long drive! thanks

hi Jason

bank 1 r/h side cylinder 1,3,5,7. and upstream, upper one

also I use jaguar IDS/SDD software and mongoose lead, this is what jaguar use and fault codes on it, usually tell you what the fault is and how to remedy it.
