7.4 DTC P0040 or P0041
DTC Descriptor
This diagnostic procedure supports the following DTCs:
• DTC P0040 – O2 Sensor Signals Not Plausible (Bank 1, Sensor 1 & Bank 2, Sensor 1)
• DTC P0041 – O2 Sensor Signals Not Plausible (Bank 1, Sensor 2 & Bank 2, Sensor 2)
Circuit Description
The engine control relay applies positive voltage to the heater ignition voltage circuits of the HO2S. The ECM applies a
pulse width modulated (PW M) ground to the heater control circuit of the HO2S through a device within the ECM called a
driver, to control the HO2S rate of heating.
The ECM applies a voltage of approximately 450 mV between the reference signal circuit and low reference circuit of the
HO2S while the sensor temperature is less than the operating range.
Once the HO2S reaches operating temperature, the sensor varies this reference signal voltage, which constantly
fluctuates between the high voltage output and the low voltage output.
• The low voltage output is 0 – 450 mV, which occurs if the air fuel mixture is lean.
• The high voltage output is 450 – 1,000 mV, which occurs if the air fuel mixture is rich.
The ECM monitors, stores and evaluates the HO2S voltage fluctuation information to determine the level of oxygen
concentration in the exhaust.
An HO2S signal not plausible or wire connector swapped DTC sets if the ECM detects the HO2S signal voltages are
heading in the opposite direction of what was commanded.
Additional Information
• Refer to 6C1-1 Engine Management – V6 – General Information for details of the HO2S system operation.
• For an intermittent fault condition, refer to 5.2 Intermittent Fault Conditions in this Section.

7.8 DTC P0116, P0117, P0118, P0125 or
P1258
DTC Descriptors
This diagnostic procedure supports the following DTCs:
• DTC P0116 – Engine Coolant Temperature Sensor Circuit Range / Performance
• DTC P0117 – Engine Coolant Temperature Sensor Circuit Low Voltage
• DTC P0118 – Engine Coolant Temperature Sensor Circuit High Voltage
• DTC P0125 – Insufficient Engine Coolant Temperature For Closed Loop Fuel Control
• DTC P1258 – Engine Coolant Over Temperature - Protection Mode Active
Circuit Description
The ECM applies a reference 5 V to the engine coolant temperature (ECT) sensor signal circuit and ground through the
low reference circuit. The ECT sensor is a variable resistor that measures the temperature of the engine coolant.
• Increased temperature in the engine coolant decreases the resistance value of the ECT sensor. This increases the
ECT sensor pull-down rate to ground. Therefore, the higher the engine coolant, the lower the signal voltage output
of the ECT sensor.
• Decreased temperature in the engine coolant increases the resistance value of the ECT sensor. This reduces the
ECT sensor pull-down rate to ground. Therefore, the lower the engine coolant temperature, the higher the signal
voltage output of the ECT sensor.
An ECT sensor DTC sets if the ECM detects the engine coolant temperature is outside the predetermined range.
Conditions for Running the DTC
DTC P0116
Runs continuously when the engine is running.
DTC P0117, P0118 and P1258
Runs continuously when the ignition is switched on.
DTC P00125
Runs continuously once the following conditions are met:
• DTCs P0112, P0113, P0117 or P0118 are not set.
• The engine is running.

Conditions for Setting the DTC
DTC P0116
The ECM detects the engine coolant temperature sensor value is 10°C less than the minimum calculated engine
temperature.
DTC P0117
The ECM detects the engine coolant temperature is greater than 140 °C for longer than 3 seconds.
DTC P0118
The ECM detects the engine coolant temperature is less than -39 °C for longer than 3 seconds.
DTC P0125
The ECM determines the calculated engine temperature by measuring the amount of airflow into the engine. This DTC
sets if the ECM detects the actual ECT sensor is not within 10ºC of the calculated engine temperature for approximately
2 – 5 minutes.
DTC P1258
The ECM detects the engine coolant temperature is greater than 131 °C for longer than 2 seconds.
Conditions for Clearing the DTC
The ECT sensor DTCs are Type B DTCs. Refer to 1.4 Diagnostic Trouble Codes in this Section, for action taken when a
Type B DTC sets and conditions for clearing Type B DTC.
Additional Information
• Refer to 6C1-1 Engine Management – V6 – General Information for details of the ECT sensor operation.
• For an intermittent fault condition, refer to 5.2 Intermittent Fault Conditions in this Section.
• DTCs P0116, P0117, P0118 and P0125 diagnostic table is developed with the assumption the engine cooling
system is functioning correctly. Therefore, rectify any engine cooling system fault conditions before proceeding
with this diagnostic table.
• Test the ECT sensor using the ECT Temperature vs. Resistance in 6C1-3 Engine Management –V6 – Service
Operations. If the engine has sat overnight, the ECT sensor should display within 3 °C of the IAT sensor values.
W hen the engine is first started, the ECT should rise steadily to about 90 °C then stabilise when thermostat opens.
• Since fault condition in a wiring connector may trigger DTCs, always test the connectors related to this diagnostic
procedure for shorted terminals or poor wiring connection before replacing any component. Refer to 8A Electrical -
Body and Chassis for information on electrical fault diagnosis.
• To assist diagnosis, refer to 3 W iring Diagrams and Connector Charts in this Section, for the system wiring

7.9 DTC P0121, P0122, P0123, P0221,
P0222,or P0223
DTC Descriptors
This diagnostic procedure supports the following DTCs:
• DTC P0121 – Throttle Position Sensor 1 Circuit Range / Performance
• DTC P0122 – Throttle Position Sensor 1 Circuit Low Voltage
• DTC P0123 – Throttle Position Sensor 1 Circuit High Voltage
• DTC P0221 – Throttle Position Sensor 2 Circuit Range / Performance
• DTC P0222 – Throttle Position Sensor 2 Circuit Low Voltage
• DTC P0223 – Throttle Position Sensor 2 Circuit High Voltage
Circuit Description
The ECM applies 5 V to the throttle position (TP) sensor 1 through the 5 V reference circuit and the ground through the
low reference circuit. TP sensor 1 and TP sensor 2 share common 5 V reference circuit and low reference circuit.
The TP sensor 1 and TP sensor 2 have individual signal circuits with opposite functionality. These signal circuits provide
the ECM with a signal voltage that is proportional to the throttle plate movement.
• The TP sensor 1 signal voltage is less than 1 V when the throttle plate is in closed position, which increases to
greater than 4 V when the throttle plate is moved to wide-open throttle.
• The TP sensor 2 signal voltage is greater than 4 V when the throttle plate is in closed position, which decreases to
less than 1 V when the throttle plate is moved to wide-open throttle.
The ECM monitors and compares the TP sensor 1 signal voltage to the TP sensor signal voltage 2. In addition, the ECM
compares the TP sensor signal to the MAF sensor signal to determine a calculated TP sensor signal.
A TP sensor DTC sets if the ECM detects a fault condition in the TP sensor signal output.
Conditions for Running the DTC
DTC P0121 runs continuously once the following conditions are met:
• The ignition voltage is greater than 7 V.
• The TP sensor 1 signal voltage is 0.17 – 4.6 V.
DTC P0122, P0123, P0222 and P0223 runs continuously once the following conditions are met:
• The ignition voltage is greater than 7 V.
• The ignition is switched on.
DTC P0221 runs continuously once the following conditions are met:
• The battery voltage is greater than 7 V.
