[jim134]

hi folks

had an engine management light come on my dash so plugged it in at my mates garage

115 coolant temp sensor/thermostat fault

so changed that and housing

now its came back on with same code

anyone any ideas???

if the coolant has been changed / thermostat / thermostat housing im guessing sensor failure.

Forgive my ignorance but is there another sensor along the way you have changed?
