P07C6 Code - Intermediate Shaft Speed Sensor 'A' Circuit High
Quick Answer
This sensor detects the rotation speed of the counter gear which indicates the output speed of the transaxle. Common causes include Faulty Speed sensor NC (Transmission Revolution Sensor), Speed sensor NC harness is open or shorted, Speed sensor NC circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P07C6 Description
The NT terminal of the ECM detects a pulse signal from the speed sensor NT (input RPM). The ECM calculates gear shifts by comparing the signal from speed sensor NT with the signal from speed sensor NC.
While the vehicle is operating in 2nd, 3rd, 4th, or 5th gear with the shift lever in D, if the input shaft speed is less than 300 rpm although the output shaft speed is more than 1000 rpm, the ECM interprets this as a fault, illuminates the MIL and stores the Diagnostic Trouble Code (DTC). P07C6 code is detected when the speed sensor input voltage is either higher than 1.9 V for 2 sec. or more.
What are the Possible Causes of the DTC P07C6?
- Faulty Speed sensor NC (Transmission Revolution Sensor)
- Speed sensor NC harness is open or shorted
- Speed sensor NC circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P07C6?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P07C6 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P07C6 Code
What does the OBDII code P07C6 mean?
The P07C6 code indicates a problem with the Intermediate Shaft Speed Sensor 'A' Circuit reporting a high voltage signal to the vehicle’s transmission control module (TCM).
What are the common symptoms of the P07C6 code?
Symptoms may include the check engine light or transmission warning light illuminating, erratic or delayed shifting, reduced transmission performance, and poor fuel economy.
What causes the P07C6 code to appear?
Common causes include a faulty intermediate shaft speed sensor, damaged or corroded wiring or connectors, a short circuit in the sensor's wiring, or a malfunctioning transmission control module.
Can I drive my car with the P07C6 code?
While the car may still be drivable, continued use with this code can lead to transmission damage or unsafe driving conditions due to erratic shifting.
How do you diagnose the P07C6 code?
Diagnosis typically involves using a scan tool to confirm the code, inspecting the sensor and related wiring for damage, and testing the sensor’s voltage output with a multimeter.
How do you fix the P07C6 code?
Repairs may include replacing the faulty intermediate shaft speed sensor, repairing damaged wiring or connectors, or reprogramming or replacing the transmission control module if needed.
How much does it cost to fix the P07C6 code?
The repair cost varies depending on the cause, but sensor replacement typically ranges from $100 to $300, while more extensive repairs like TCM replacement can cost $500 or more.
Can a low battery cause the P07C6 code?
A low or failing battery is unlikely to directly cause this code, but it could exacerbate electrical issues that affect the sensor or TCM.
Is the P07C6 code specific to a certain vehicle make or model?
No, the P07C6 code is a generic OBDII code and can appear in vehicles equipped with an intermediate shaft speed sensor, though the exact repair process may vary by make and model.
Can clearing the code resolve the P07C6 issue?
Clearing the code may temporarily turn off the warning light, but it won’t fix the underlying issue causing the code to appear. Proper diagnosis and repair are necessary.
