P097

Sensor Circuit:

DESCRIPTION
This diagnostic test is to detect the vehicle transaxle being placed in gear under conditions that may cause damage to the vehicle powertrain or create an unsafe condition. When such a condition exists, Code P097 is set and engine power will be reduced by disabling fuel to individual cylinder.

DIAGNOSTIC CIRCUIT CHECK
^ The primary purpose of this code is to detect an action of the driver that could cause an unsafe condition or damage to the vehicle.
^ This code can be driver induced by shifting from park or neutral to drive or reverse with a throttle angle of 200 or greater.
^ Fuel injectors 2, 3, 5 and 8 will be disabled when the code sets.
^ Check Throttle Position (TP) sensor for proper operation.
^ Fuel injectors will not be reenabled until one of the following conditions is met:
- Throttle position switch is closed.
OR
- Throttle angle is less than 3 degrees and vehicle speed is 8 mph or less.

TEST CONDITIONS
1. Codes P021, P022 and P070 not set.

FAILURE CONDITIONS
1. Gear selection from Park or Neutral to Drive or Reverse.
2. Vehicle speed less than 6 mph.
3. Engine speed greater than 2000 rpm.
4. Throttle angle of 20 degrees or greater (if Code P097 is already stored in history, use a throttle angle of 16 degrees or greater).
5. Condition 1 through 4 are valid for 0.3 second.

ACTION TAKEN
1. Powertrain Control Module (PCM) will disable fuel to individual cylinders to reduce engine power.
