ABS Pressure Sensor Fault

[ally_raf]

I have the 5E20 Pressure Sensor 1 fault code plus all the usual symptoms (dash alarms etc). I’ve read all the related threads and happy to buy a replacement and fit. I’ve not seen anyone make any reference to working out which is sensor 1 and which is sensor 2. Is there an easy way of working this out or is it a case of trial and error?

I think #1 is nearest the bulkhead, #2 nearest the front of the car but not 100% sure. I ended up changing both of mine for peace of mind, given the part was so cheap.

You can use your scanner and a process of elimination to work it out. Clear the codes and just unplug one sensor at a time or swap the plugs over and you'll soon work it out. If it's the back one it's a pain to access with tools unless you have the appropriate size deep socket (IIRC 27mm) without first removing the front one. As a result of this you maybe better just swapping out the pair of them. The sensors are really pricey from the dealers at £100+ but aftermarket ones can be had on Ebay for less than £10 each with folks having reported good results with them. At that price you might aswell swap out the pair of them.

Thanks for the feedback. I’ve read good things about non-OEM sensors from eBay. Will just replace both
