P0707 Code: Transmission Range Sensor “A” Circuit Low

Is your vehicle showing symptoms relating to the transmission? You should check if your vehicle’s powertrain control module (PCM) has stored trouble codes by connecting a scan tool. If the P0707 code has been triggered, this article will inform you about the code’s definition and common causes and symptoms.

What Does the P0707 Code Mean?

Diagnostic trouble code P0707 is defined as Transmission Range Sensor “A” Circuit Low. This code triggers when either the transmission range sensor or neutral safety switch isn’t sending a high enough voltage signal to the powertrain control module (PCM). This code can also mean the transmission range sensor or neutral safety switch isn’t returning any voltage.

The transmission range sensor is used by the PCM to collect information about the position of the gear selector. This information is used to regulate hydraulic pressure within the transmission. The sensor also prevents the engine from being started when the gear lever is set to drive or reverse.

Note: The definition of the P0707 code can be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P0707 Code?

The problems that trigger the P0707 code can be caused by the following issues:

• Malfunctioning transmission range sensor
• Misadjusted transmission range sensor
• Malfunctioning neutral safety switch
• Damaged shift linkage
• Faulty PCM
• Faulty wiring

What are the Common Symptoms of the P0707 Code?

Your vehicle might exhibit the following symptoms when the P0707 code is triggered:

• The engine refuses to start
• The engine starts in gear, which can lead to sudden acceleration
• Erratic shifting transmission
• Vehicle enters limp mode
• Illuminated check engine light

How to Diagnose the P0707 Code

Identifying the main cause of the P0707 code can be difficult because there are several components that you need to check. You might need special knowledge or tools to access and test parts like the transmission range sensor and the PCM. If you want to properly diagnose the P0707 code in your vehicle, it’s best to consult a professional.

How to Fix the P0707 Code

Want to fix the problems causing the P0707 code to trigger? Unfortunately, there isn’t a set procedure that will guarantee a solution. Since vehicle models are designed differently, the repair procedures for a DTC can vary.

The first step in repairing a DTC is accurately diagnosing the problem. You should only start doing repairs once you’ve identified the main problem. Otherwise, you might fail to focus on the faulty component. After finding the culprit, you can look at reputable internet repair resources and how-to guides.

If you don’t have much experience diagnosing DTCs, you should consult a professional mechanic.
