Symptom:
P0070-AMBIENT AIR TEMPERATURE CIRCUIT SIGNAL VOLTAGE TOO HIGH
When Monitored and Set Condition:
P0070-AMBIENT AIR TEMPERATURE CIRCUIT SIGNAL VOLTAGE TOO HIGH
When Monitored: With the ignition on.
Set Condition: When the ECM detects voltage above 4.83 volts on the Ambient Air Temperature Sensor Signal circuit.
POSSIBLE CAUSES
INTERMITTENT CONDITION
AMBIENT AIR TEMP SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE AMBIENT AIR TEMP SENSOR GROUND CIRCUIT OPEN
AMBIENT AIR TEMP SENSOR SIGNAL CIRCUIT OPEN
MAF/AMBIENT AIR TEMPERATURE SENSOR
ENGINE CONTROL MODULE
1 NOTE: If the ECM detects and stores a DTC, the ECM also stores the All engine/vehicle operating conditions under which the DTC was set. Some of
these conditions are displayed on the DRB at the same time the DTC is
displayed.
NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC. Turn the ignition on.
With the DRB, erase ECM DTCs.
Turn the ignition off, then on.
With the DRBIII, read the ECM DTCs. Did this DTC set again?
Yes → GoTo 2 No → GoTo 6

Test Note: All symptoms listed above are diagnosed using the same tests. The title for the tests will be P2120-ACC PEDAL POSITION SENSOR 1 CKT PLAUSIBILITY WITH BRAKE SWITCH.
When Monitored and Set Condition:
P2120-ACC PEDAL POSITION SENSOR 1 CKT PLAUSIBILITY WITH BRAKE SWITCH
When Monitored: With the engine speed above 790 rpm and vehicle speed above 0 km/h.
Set Condition: The ECM detects the Accelerator Pedal and the Brake Pedal have been depressed at the same time for longer than the allowable time.
P2120-ACC PEDAL POSITION SENSOR 1 CKT SIGNAL VOLTAGE TOO HIGH
When Monitored: With the ignition on.
Set Condition: The ECM detects voltage on the Accelerator Pedal Position Sensor Signal circuit above 4.67 volts for 0.32 second.
P2120-ACC PEDAL POSITION SENSOR 1 CKT SUPPLY VOLTAGE TOO HIGH OR LOW
When Monitored: With the ignition on.
Set Condition: The Accelerator Pedal Position Sensor 1 5-Volt Supply voltage is too high or too low.
P2125-ACC PEDAL POSITION SENSOR 2 CIRCUIT PLAUSIBILITY WITH 1 CIRCUIT
When Monitored: With the ignition on.
Set Condition: The ECM determines that the APP Sensor 1 and APP Sensor 2 signals do not agree.
