P0116 WTS COOL _SENS
Sensor out of
range
Yes No Return to idle
Possible causes:
Damaged sensor, damaged circuit wires, damaged connector, damaged ECU pins. ECU failure.
Service action:
Check for resistance approx. 2280 ohms to 2736 ohms at temperature of 19 to 21°C (66 to 70°F) between system circuits 4-9 and 4-11.
P0217
WTS COOL_RED
Overheat
warning
Yes No
As soon as fault is
not present
Possible causes:
Engine overheated, damaged sensor.
Service action:
Check for debris or blockage in cooling system. Check for resistance approx. 2280 ohms to 2736 ohms at temperature of 19 to 21°C
(66 to 70°F) between system circuits 4-9 and 4-11.
P0110 MATS MCT_SENS
Sensor out of
range
Yes No Return to idle
Possible causes:
Damaged sensor, damaged circuit wires, damaged connector, damaged ECU pins. ECU failure.
Service action:
Check for resistance approx. 2280 ohms to 2736 ohms at temperature of 19 to 21°C (66 to 70°F) between system circuits 4-16 and 4-19.
P0106 MAPS MAP
Sensor out of
range
Yes No Return to idle
Possible causes:
Check sensing port for dirt or blockage. Sensor failure, unexpected reading at idle. Sensor fallen out of housing. Leaking Inlet system,
ECU failure.
Service action:
Check system circuits 3-3, 3-6, 3-7. Check sensor connector for 5 volts on pin 1 and 0 volts on pin 3 and 0 volts on pin 2. Check
sensor housing is correctly inserted into manifold.
P0105 MAPS MAP_ATM
Bad atmospheric
reading
Yes No
Full reset. Key
off and on
Possible causes:
Check sensing port for dirt or blockage, damaged sensor, damaged circuit wires, damaged connector, damaged ECU pins. ECU failure.
Service action:
Check system circuits 3-3, 3-6, 3-7. Check sensor connector for 5 volts on pin 1 and 0 volts on pin 3 and 0 volts on pin 2.
P1400
EGTS EXH_SENS
