P1519

CIRCUIT DESCRIPTION
The Throttle Position (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, or P1518 are not set.
^ The ignition switch is in the crank or the run position.

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

ACTION TAKEN WHEN THE DTC SETS
^ The control module stores the DTC information into memory when the diagnostic runs and fails.
^ The Malfunction Indicator Lamp (MIL) will not illuminate.
^ The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure Records.
^ The driver information center, if equipped, may display a message.

CONDITIONS FOR CLEARING THE DTC
^ A current DTC "Last Test Failed" clears when the diagnostic runs and passes.
^ A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
^ Use a scan tool in order to clear the DTC.

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

TEST DESCRIPTION

Steps 1-5:

The number below refers to the step numbers on the diagnostic table.
5. When the TAC module detects a condition within the Electronic Throttle Control (ETC) system the Powertrain Control Module (PCM) receives a message across serial data and more than 1 ETC system related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing 1 individual condition may correct more than 1 DTC. Keep this in mind when reviewing captured DTC info.
