Most auto repair shops typically charge between $75 and $150 per hour for their services. These factors contribute to the overall cost of resolving the fault code.

The P1810 fault code refers to a problem with the Transmission Fluid Pressure (TFP) manual valve position switch in the automatic transmission. This switch consists of five pressure switches and a Transmission Fluid Temperature (TFT) sensor combined into one unit. It is mounted on the valve body. The Powertrain Control Module (PCM) supplies ignition voltage for each range signal.

By grounding one or more of the circuits through the pressure switches, the PCM can detect which manual valve position is selected. It compares the voltage combination of the switches to a table stored in memory. However, the TFP manual valve position switch cannot distinguish between PARK and NEUTRAL because the valve body pressures are the same.

When the engine is off and the ignition switch is in the RUN position, the switch indicates PARK or NEUTRAL.

Disconnecting the AT inline 20-way connector removes the ground potential for the range signals, causing D2 to be indicated when the engine is off and the ignition switch is in the RUN position.

What are the possible causes of the p1810 fault code in an automobile?

If you’re seeing the p1810 fault code in your automobile, it could be due to a few possible causes. One of them is a faulty Automatic Transmission Fluid Pressure (TFP) Manual Valve Position Switch. Another cause could be an open or shorted TFP Valve Position Switch harness. Additionally, a poor electrical connection in the TFP Valve Position Switch circuit could also be the culprit. 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.

How can I visually inspect the wiring harness and connectors to fix the p1810 fault code?

If you’re dealing with the p1810 fault code and your engine light is on, it’s time to take a closer look at the wiring harness and connectors. The most likely cause of this issue is a faulty Automatic Transmission Fluid Pressure (TFP) Manual Valve Position Switch or an open or shorted TFP Valve Position Switch harness. To fix it, visually inspect the wiring harness and connectors for any signs of damage. Check for broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to also check for any poor electrical connections.

What should I look for when checking for damaged components and connector pins to resolve the p1810 fault code?

When resolving the p1810 fault code, start by checking for damaged components and connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins on the connectors. By doing this, you can identify any issues with the Automatic Transmission Fluid Pressure (TFP) Manual Valve Position Switch or the TFP Valve Position Switch circuit. This will help you determine the cause of the fault code and take appropriate action to fix it.
