P1519

CIRCUIT DESCRIPTION
The TP sensor 1 signal is fed into a multiplier (5X) to produce a high resolution calculated TP sensor voltage. This higher resolution TP sensor voltage is used for actuator control in low throttle angle conditions.

CONDITIONS FOR RUNNING THE DTC
^ DTCs P0606, P1517, P1518 are not set.
^ The ignition switch is in the crank or run position.

CONDITIONS FOR SETTING THE DTC
The high resolution TP sensor is out of range.

ACTION TAKEN WHEN THE DTC SETS
^ The PCM will not illuminate the Malfunction Indicator Lamp (MIL).
^ The PCM will store conditions which were present when the DTC set as Failure Records data only. This information will not be stored as Freeze Frame data.

CONDITIONS FOR CLEARING THE MIL/DTC
^ A history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
^ The DTC can be cleared by using a scan tool.

DIAGNOSTIC AIDS
If the DTC is determined to be intermittent, reviewing the Fail Records can be useful in determining when the DTC was last set.

TEST DESCRIPTION

Diagnostic Chart:

The numbers below refer to the step numbers on the diagnostic table.
5. When the TAC module detects a problem within the ETC System the PCM receives a message across serial data and more than one ETC System related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing one individual problem may correct more than one DTC. Keep this in mind when reviewing captured DTC info.
