156 2.0JTS Lambda Sensors
I have a bit of a techie question - I hope somebody here can help out ! I have a 2002 2.0JTS with just over 50K miles. The infamous Motor Control Fault light came on the other day. My local garage plugged me in, and it showed:
P0141/P1141 Heated Oxygen Sensor (HO2S) 2, bank 1, heater control - circuit malfunction
He called it a 'sluggish' sensor. You could see the readouts from the other sensors responding to throttle change, but this one stayed pretty much the same. We reset the code, but it came on again about 10 miles down the road.
Can anybody tell me which sensor this is - I understand there are 4 sensors - 2 before the cat., and 2 after ? Even better, where's a good place to get hold of one ?
