156 2.5 V6 Q4 faults 1999
So my 156 has started to play up again this time the speedo has stopped working and the ABS light is on. I have run Alfadiag and it came up with 4 fault codes the one relating to this i belive is P0500 which is "Vehicle speed sensor malfunction" im guessing its an ABS sensor as i belive these run the speedo as well any ideas which one to check.
also the other faults are P0135 & P0155 which are "O2 sensor heater circuit malfunction" sensor 1 on both A & B bank is this the lambda sensor if not any one show me where these are with a pic if possible.
The final fault is U1600 which i belive is an immobiliser fault which is a intermittant fault which i know how to work around so not worried with this one.
Any advice or pointers welcomed cheers.
