The P099B fault code refers to the Shift Solenoid ‘G’ Control Circuit being detected as low by the Transmission Control Module (TCM).

The TCM constantly monitors the signal from the Shift Solenoid to ensure it is operating within the factory specifications.

When the TCM detects that the Shift Solenoid ‘G’ Control Circuit is operating at a lower level than expected, it triggers the P099B fault code. This fault code indicates a potential issue with the control circuit of the Shift Solenoid ‘G’, which may affect the shifting performance of the transmission. It is important to address this issue promptly to prevent further damage and ensure smooth operation of the transmission.

What are the possible causes for the automobile fault code p099b?

If you see the engine light or service engine soon warning light on, the fault code P099B could be the culprit. This code is often caused by a faulty shift solenoid ‘G’, an open or shorted shift solenoid ‘G’ harness, or a poor electrical connection in the shift solenoid ‘G’ circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes listed 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 ‘G’, an open or shorted Shift Solenoid ‘G’ harness, or a poor electrical connection in the Shift Solenoid ‘G’ circuit. Check for any damaged components and look closely for broken, bent, pushed out, or corroded pins in the connectors. This thorough inspection will 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 ‘G’ 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 check for broken, bent, pushed out, or corroded connector pins. These issues can lead to poor electrical connections and contribute to the problem. Take the time to thoroughly examine these areas to ensure a proper fix.
