DIAGNOSTIC TROUBLE CODE (DTC) P0122
THROTTLE POSITION SENSOR LOW VOLTAGE
Circuit Description
The Engine Control Module (ECM) supplies a 5 volt ref-
erence voltage signal and a ground to the Throttle Posi-
tion (TP) sensor. The TP sensor sends a voltage signal
back to the ECM relative to the throttle plate opening.
The voltage signal will vary from approximately 0.33
volts at closed throttle, to over 4.3 volts at Wide Open
Throttle (WOT).
The TP signal is used by the ECM for fuel control and for
most of the ECM controlled outputs. The TP signal is
one of the most important inputs used by the ECM for
fuel control and most of the ECM controlled outputs.
Conditions for Setting the DTC

TP sensor voltage indicates a throttle voltage less
than 0.14 volts.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
A history DTC is stored.

The TP angle will default to 0% when the vehicle
speed is less than 3 km/h (2 mph) and 10% when the
vehicle speed is greater than 3 km/h (2 mph). The
scan tool will not display the default value.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.

Disconnecting the ECM battery feed for more than 10
seconds.
Diagnostic Aids
If the DTC P0122 cannot be duplicated, the information
included in the Freeze Frame data can be useful. Use a
scan tool information data to determine the status of the
DTC. If the dc occurs intermittently, using the Diagnostic
table may help isolate the problem.

THROTTLE POSITION SENSOR HIGH VOLTAGE
Circuit Description
The Engine Control Module (ECM) supplies a 5 volt ref-
erence voltage signal and a ground to the Throttle Posi-
tion (TP) sensor. The TP sensor sends a voltage signal
back to the ECM relative to the throttle plate opening.
The voltage signal will vary from approximately 0.33
volts at closed throttle, to over 4.3 volts at Wide Open
Throttle (WOT).
The TP signal is used by the ECM for fuel control and for
most of the ECM controlled outputs. The TP signal is
one of the most important inputs used by the ECM for
fuel control and most of the ECM controlled outputs.
Conditions for Setting the DTC

TP sensor voltage indicates a throttle voltage greater
than 4.9 volts.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

A history DTC is stored.

The TP angle will default to 0% when the vehicle
speed is less than 3 km/h (2 mph) and 10% when thevehicle speed is greater than 3 km/h (2 mph). The
scan tool will not display the default value.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.

Disconnecting the ECM battery feed for more than 10
seconds.
Diagnostic Aids
If the DTC P0123 cannot be duplicated, the information
included in the Freeze Frame data can be useful. Use a
scan tool information data to determine the status of the
DTC. If the dc occurs intermittently, using the Diagnostic
table may help isolate the problem.
With ignition ON and the throttle at closed position, the
voltage should read between 0.2 and 0.90 volts and in-
crease steadily to over 4.3 volts at WOT.
DTCs P0123 and P0113 stored at the same time could
be result of an open sensor ground circuit.

DIAGNOSTIC TROUBLE CODE (DTC) – P0131 OXYGEN SENSOR LOW
V O LTA G E
Circuit Description
The engine control module (ECM) supplies a voltage of
about 450m volts between the ECM terminals 44 and
13. The oxygen (O
2) sensor varies the voltage within a
range of about 1volt if the exhaust is rich, down to about
100mm volts if the exhaust is lean. The O
2 sensor is like
an open circuit and produces no voltage when it is below
350°C(600°F). An open O
2 sensor circuit or a cold O2
sensor causes “open loop” operation.
Conditions for Setting the DTC
(Case A)

The engine controls system is in closed loop.

Engine speed is less than 6,000rpm.

The oxygen sensor voltage is below 0.07V for at least
40seconds.

DTCs P0107, P0108, P0117, P0118, P0122, P0123,
P0335, P0336, P0341, P0342, P0400, P0404,
P0405, P0406, P0445, P0444 are NOT SET.
(Case B)

The engine controls system is in closed loop.

Engine speed is less than 6,000rpm.

The oxygen sensor voltage is between 0.352 and
0.499 at least 10seconds.
Action Taken when the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.
The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

A history DTC is stored.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.

Disconnecting the ECM battery feed for more than 10
seconds.
Diagnostic Aids
Normal scan tool voltage varies between 0.1volts and
0.9 volts while in closed loop.
Inspect the oxygen (O
2) sensor wire. The O2 sensor
may be positioned incorrectly and contacting the ex-
haust manifold.
Check for an intermittent ground in the wire between the
O
2 sensor and the engine control module.
Perform an injector 2alance test to determine if a re-
stricted fuel injector may be causing the lean condition.
Vacuum of crankcase leaks will cause a lean running
condition.
An exhaust manifold gasket leak of a cracked exhaust
manifold may cause outside air to be pulled into the ex-
haust and past the sensor.
