When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p099f fault code.

  • The symptoms of the automobile fault code p099f include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p099f can be caused by a faulty Shift Solenoid ‘H’, an open or shorted Shift Solenoid ‘H’ harness, or a poor electrical connection in the Shift Solenoid ‘H’ circuit.

  • The fault code P099F can be caused by the following: a faulty Shift Solenoid ‘H’, an open or shorted Shift Solenoid ‘H’ harness, and a poor electrical connection in the Shift Solenoid ‘H’ circuit.

To fix the automobile fault code p099f, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p099f, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The automobile fault code p099f diagnosis and fixing cost is influenced by the estimated repair time of 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services.

The P099F fault code refers to the Shift Solenoid ‘H’ Control Circuit being too high.

This code is set by the Transmission Control Module (TCM) when it detects that the Shift Solenoid is not operating within the factory specifications. The Shift Solenoid is responsible for controlling the flow of transmission fluid, which in turn determines the gear shifting in the vehicle.

When the TCM detects that the Shift Solenoid ‘H’ Control Circuit is too high, it means that there is an issue with the electrical circuit that controls the solenoid. This fault code indicates that there may be a problem with the wiring, connectors, or the solenoid itself. It is important to address this issue promptly, as it can lead to improper gear shifting and potential damage to the transmission if left unresolved.

A qualified technician should diagnose and repair the underlying cause of the P099F fault code to ensure the proper functioning of the transmission system.

What are the possible causes for the automobile fault code P099F?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P099F might be the culprit. This code is often caused by a faulty shift solenoid ‘H’, an open or shorted shift solenoid ‘H’ harness, or a poor electrical connection in the shift solenoid ‘H’ circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look out for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes mentioned above for a comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the issue?

To fix the issue of the Engine Light being ON or the Service Engine Soon Warning Light, start by visually inspecting the wiring harness and connectors. This can help identify the cause, which could be a faulty Shift Solenoid ‘H’, an open or shorted Shift Solenoid ‘H’ harness, or a poor electrical connection in the Shift Solenoid ‘H’ circuit. Check for any damaged components and look closely for broken, bent, pushed out, or corroded pins in the connectors. This thorough inspection can help pinpoint the problem and guide you towards the appropriate fix.

What should I look for when checking for damaged components or corroded connector pins?

When troubleshooting a faulty shift solenoid ‘H’ that is causing the engine light to turn on, it’s important to visually inspect the wiring harness and connectors. Look for any damaged components and pay close attention to the connector pins. Check for any signs of corrosion, as well as broken, bent, or pushed out pins. These issues can often be the cause of poor electrical connections and can be easily identified during a thorough inspection.

p099f error fault code explained

If your engine light is on and you’re getting the P099F fault code, it could be due to a faulty Shift Solenoid ‘H’, an open or shorted Shift Solenoid ‘H’ harness, or a poor electrical connection in the Shift Solenoid ‘H’ circuit.
