Transmission Fluid Pressure Sensor/Switch F Circuit Intermittent

Where it lives

For P0996, the circuit described runs through the sensor. The description of P0996 reports a fault at the sensor.

Check these first

• A transmission fluid pressure sensor F connector losing contact
• Chafed wiring in the sensor F harness
• A sensor F that fails when hot
• Water in the sensor F connector
• A PCM connection fault

What to do next

1. Road test and watch transmission fluid pressure sensor F data
2. Wiggle test the sensor F connector and harness
3. Measure the sensor F signal hot
4. Inspect the connector for water
5. Replace the sensor if the signal drops
6. Clear the code and retest
