Failed emms test with hi co of 6.25 at idle rising to 8.90 at 2500.
Scan show fault code as P0125 : insufficient coolant temperature for closed fuel control,ect excessive time to close loop fuel control.
Live data shows CTS reading 89-92,O2 sensor rising and falling as expected,fueling status open loop.
Disconnect fan and allowed temp to rise to 108 c and still no change to loop status.
I have little info on this vehicle,I note that there is a third wire from the CTS,yellow in color what is its function? The others are brown. And red with blue trace.
Customer he has been aware of the Mil light for the past three months and (has his own scanner!) he has changed the following items to no avail.
Customer has prior fitted, CTS,O2sensor,thermostat all OE kit.
Our Launch shows a memory reset function which when selected returns me to the live readings selection screen with a prompt to check the manual to see if this function is available I presume they mean the Toyota manual,is this function available on this model?
I am wondering if it is ECU related,has anyone out there any suggestions and more importantly has anyone a wiring diagram or pin-out details on this vehicle.
ECU Details are
89661-52060
