[SOLVED] P0706 Code: Fixing Transmission Range Sensor Circuit Performance Issue

The automobile fault code P0706 indicates a problem with the ParkNeutral Position (PNP) switch.

This can be identified by the Engine Light or Service Engine Soon Warning Light turning on.

The cause of this fault code can be a faulty or misadjusted PNP switch, an open or shorted PNP switch harness, or a poor electrical connection in the PNP switch circuit.

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated to be around 1.0 hour. To interpret the fault code, refer to the “Possible Causes” listed above and follow the recommended steps for inspection and repair.

The factors influencing the cost of diagnosing and fixing the automobile fault code P0706 include the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P0706 fault code refers to a problem with the transmission range sensor circuit. This sensor is part of the ParkNeutral Position (PNP) switch, which detects the position of the selector lever when it is in the N or P shift position.

It then sends a signal to the Transmission Control Module (TCM). If the transmission range switch detects the selector lever position and sends a signal to the TCM, the Diagnostic Trouble Code (DTC) will be set, indicating an issue with the sensor circuit. This fault code is known as P0706 – Transmission Range Sensor Circuit Performa.

What are the possible causes of the automobile fault code P0706?

If you see the engine light or service engine soon warning light on, the fault code P0706 might be the culprit. This code is often caused by a faulty park/neutral position (PNP) switch, a misadjusted switch, an open or shorted switch harness, or poor electrical connections in the switch 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 mentioned above for a more comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the P0706 fault code?

If you’re dealing with the P0706 fault code and notice that your engine light is on, it’s time to take action. The most common causes of this code are a faulty or misadjusted Park/Neutral Position (PNP) switch, an open or shorted PNP switch harness, or a poor electrical connection in the PNP switch circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken, bent, pushed out, or corroded pins. This simple step can help you identify and resolve the problem.

What should I look for when checking for damaged components or corroded connector pins to resolve the P0706 fault code?

When resolving the P0706 fault code, start by checking for damaged components or corroded 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 that may be causing the fault code and take the necessary steps to fix them.

p0706 error fault code explained

If your engine light is on or you see a service engine soon warning, it could be due to a faulty ParkNeutral Position (PNP) switch, a misadjusted switch, an open or shorted harness, or a poor electrical connection.

To fix this, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
