P096

Transaxle Range Switch Circuit:

DESCRIPTION
This diagnostic test checks for unusually large throttle position at low vehicle speed with the brake being applied. The primary purpose of this code is to record snapshot data and alert the driver that this driving condition could damage the vehicle drivetrain or create an unsafe condition. If such a driving condition exists, Code PO96 will set.

DIAGNOSTIC CIRCUIT CHECK

NOTE: Most occurrences of this code will be due to the application of the brake and accelerator at the same time.

Torque Converter Clutch (TCC) brake switch, transaxle range switch, Vehicle Speed Sensor (VSS) and Throttle Position (TP) sensor failures should be caught by other diagnostic codes. If any of the checks below fail, see the indicated code chart for diagnosis.

^ Check operation of brake switch by using TCC brake switch input test (input test PI71).

^ Check operation of TP sensor by monitoring TP sensor degrees while moving throttle (see codes PO21, P022, and PO70).

^ Check for correct MPH indication on instrument panel (see code P024).

^ Check operation of transaxle range switch by monitoring "AUTO" status light while shifting in and out of P/N (refer to code PO91).

TEST CONDITIONS
Codes P021, PO22 and P024 not set.

FAILURE CONDITIONS
1. Brake applied.

2. Transaxle in DRIVE or REVERSE.

3. Vehicle speed 5 mph or less.

4. Throttle position 65 degrees or greater for 12 seconds.

ACTION TAKEN
1. Powertrain Control Module (PCM) turns "ON" the "Service Engine Soon" Malfunction Indicator Lamp (MIL).

2. The "Service Engine Soon" MIL will remain "ON" for 15 seconds after Code PO96 becomes history.
