Just been out to the vr and got all these fault. *00522 engine coolant sensor 27-10 implausible signal intermittant. *01259 fuel pump relay (j17) 37-10 open or short to ground intermittent. Is the coolant temp sensor the blue one on the thermostat housing? My intake temp sensor is reading 70+ c on idle and only drops to about 60 when driving, is this normal? And has anybody got a part no for a odb1 ecu?
