P07C5 Scion Code - Intermediate Shaft Speed Sensor 'A' Circuit Low
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 P07C5 Scion 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). P07C5 code is detected when the speed sensor input voltage is below 0.1 V for 2 sec. or more.
What are the Possible Causes of the DTC P07C5 Scion?
- 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 P07C5 Scion?
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?

Frequently Asked Questions about P07C5 Scion Code
What does the OBDII code P07C5 mean for a Scion?
The code P07C5 indicates an issue with the Intermediate Shaft Speed Sensor 'A' Circuit, specifically a "low" signal being detected, which may affect transmission operation.
What are the common symptoms of code P07C5 in a Scion?
Symptoms can include erratic shifting, transmission slipping, poor acceleration, and the check engine light being illuminated.
What causes the P07C5 code to trigger in a Scion?
This code can be caused by a faulty intermediate shaft speed sensor, damaged wiring, loose sensor connectors, or a malfunctioning transmission control module (TCM).
How can I diagnose the P07C5 code in my Scion?
Diagnosis involves inspecting the sensor and its wiring for damage or disconnections, testing the sensor itself, and scanning the TCM for additional related error codes.
Can I drive my Scion with the P07C5 code active?
While the car may still be drivable, driving with this code active can lead to worsening transmission issues and should be addressed promptly to avoid further damage.
How do I fix the P07C5 error code on a Scion?
Repairs may include replacing the intermediate shaft speed sensor, repairing damaged wiring or connectors, or reprogramming or replacing the TCM if necessary.
How much does it cost to repair the P07C5 code on a Scion?
Costs can vary widely, but replacing the sensor typically costs $150-$400, while wiring repairs or TCM replacement may cost more depending on labor and parts.
What tools are needed to fix the P07C5 code on a Scion?
You will need an OBDII scanner, a multimeter for testing electrical components, and basic tools for removing and replacing the sensor or wiring.
Can a dirty sensor cause the P07C5 code in a Scion?
Yes, debris or contamination on the intermediate shaft speed sensor can interfere with its operation and trigger this code.
Does the P07C5 code always mean the sensor is bad?
No, the issue could also stem from wiring problems, connector issues, or faults in the TCM rather than the sensor itself.
