No idea, havent bothered to check just had it reset at the local mechanics.
I can purchase a new 4 wire universal that matches the 4 wires on mine, however i dont have the right socket to fit the sensor, so my progress has halted.

Anyone able to remove/fit and reset the code? =P haha planning on just booking it into the mechanics to do both i guess, and ill supply the sensor so its hopefully cheaper.
