This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble getting a steady signal from a sensor that checks the pressure of the transmission fluid. It's like trying to watch a TV show with a bad signal that keeps cutting out.
The P0996 code is triggered when the Powertrain Control Module (PCM) detects an intermittent signal from the transmission fluid pressure sensor or switch labeled 'F'. This sensor monitors the pressure of the transmission fluid to ensure the transmission operates correctly.
The transmission fluid pressure sensor/switch 'F' is responsible for monitoring the hydraulic pressure within the transmission. An intermittent circuit indicates that the electrical signal from this sensor is not consistent, which can affect the transmission's operation. This could be due to wiring issues, a failing sensor, or a problem with the PCM.
• Check Engine Light is on
• Erratic or harsh shifting
• Transmission slipping or not engaging properly
• Faulty transmission fluid pressure sensor/switch
• Damaged or corroded wiring/connectors
• Malfunctioning Powertrain Control Module (PCM)
PCM: Powertrain Control Module, the car's main computer for engine and transmission management.
Transmission Fluid: A liquid used to lubricate and cool the transmission.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the transmission fluid pressure sensor/switch for proper operation.
• Repair or replace damaged wiring/connectors.
• Replace the faulty transmission fluid pressure sensor/switch.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular transmission fluid checks and changes
• Inspect wiring for wear during routine maintenance
• Address Check Engine Light issues promptly
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you notice transmission issues.
Check your vehicle's warranty for coverage on transmission components.
This code has been associated with vehicles experiencing intermittent transmission issues, often resolved by addressing wiring or sensor faults.
Moderate – While the vehicle may still be drivable, unresolved issues can lead to more severe transmission problems.
Driving with a malfunctioning transmission can be unsafe. Address the issue promptly to avoid potential accidents.
• Vehicle at operating temperature
• Transmission in gear
The transmission fluid pressure sensor is typically located on the transmission housing.
Q: Can I drive my car with a P0996 code?
A: While you may be able to drive the car, it's not recommended as it can lead to further transmission damage.
Q: How do I reset the Check Engine Light after fixing the issue?
A: You can use an OBD-II scanner to clear the code, or it may reset after several driving cycles if the issue is resolved.
