Diagnostic trouble code P1713 is a manufacturer-specific powertrain fault code. Because it is manufacturer-specific, its exact definition depends entirely on the vehicle make, model, and application.
Exact vehicle application must be verified before diagnosis. The code identifies a detected condition in a specific subsystem, but further testing is required to identify the root cause.
Quick Navigation
Key Takeaways
- P1713 is a manufacturer-specific code, meaning its definition varies between automakers like Volkswagen, Ford, and Chrysler.
- On certain VW and Audi applications, it indicates a hydraulic pressure sensor implausible signal fault.
- On Ford applications, it indicates a transmission fluid temperature sensor range failure.
- On Chrysler applications, it indicates a restricted manual valve fault.
- Diagnosis requires verifying the exact factory definition and testing the relevant sensors or valve body components.
P1713 Code Description and Implications
Because P1713 is manufacturer-specific, there is no single universal definition. This error code identifies a detected condition, but the exact monitored system depends on the vehicle make and model.
Some Volkswagen and Audi applications: P1713 indicates a “Hydraulic Pressure Sensor 2 (G194) Implausible Signal” fault, meaning the module detects contradictory pressure data.
Certain Ford and Lincoln applications: P1713 indicates a “Transmission Fluid Temperature (TFT) Sensor In Range Failure,” pointing to an unexpected temperature reading during self-tests.
Some Chrysler, Dodge, and Jeep applications: P1713 indicates a “Restricted Manual Valve in T2 Range” fault, meaning the valve body is not directing fluid correctly.
Common Causes of the P1713 Code
The underlying cause depends entirely on the verified factory definition for the specific vehicle application.
For VW and Audi applications, possible causes include a failing G194 hydraulic pressure sensor, damaged wiring, or internal valve body wear.
For Ford applications, causes may involve a failing TFT sensor (often integrated into the internal harness), damaged wiring, or low transmission fluid.
For Chrysler applications, causes can include a restricted manual valve, a stuck solenoid switch valve, or mechanical wear inside the valve body.
Symptoms Associated With P1713
Symptoms vary widely depending on the underlying system fault and the vehicle manufacturer.
On applications with a hydraulic pressure sensor fault, symptoms can include harsh shifting, delayed engagement, or the transmission entering a limp mode.
On applications with a TFT sensor fault, symptoms may include erratic torque converter clutch operation or incorrect shift timing.
On Chrysler applications with a restricted manual valve, symptoms may include the transmission unexpectedly shifting into neutral or a loss of reverse gear.
Diagnosing the P1713 Trouble Code
Diagnosis must begin by confirming the exact factory definition for the specific make, model, and year.
For VW and Audi applications, technicians monitor live hydraulic pressure data and test the G194 sensor circuit for opens or shorts.
For Ford applications, technicians compare the TFT sensor data to the engine coolant temperature at startup and test the sensor resistance.
For Chrysler applications, technicians check the transmission fluid pressure switches, inspect the manual valve linkage, and evaluate the valve body condition.
Repairing the P1713 Issue
Repairs must follow confirmed diagnosis based on the specific vehicle application.
If a G194 sensor or circuit fault is confirmed on a VW or Audi application, the sensor must be replaced or the wiring repaired.
If a TFT sensor fault is confirmed on a Ford application, the internal harness or lead frame containing the sensor must be replaced.
If a restricted manual valve is confirmed on a Chrysler application, the valve body must be serviced or replaced, and the linkage repaired.
Cost Considerations for P1713 Repairs
Repair costs depend entirely on the confirmed root cause, component accessibility, and local labor rates.
Replacing an external pressure sensor may require minimal labor depending on accessibility.
Conversely, replacing an internal TFT sensor harness or servicing a transmission valve body requires dropping the transmission pan and significant labor.
Prevention Strategies for Future Occurrences
Some electrical and hydraulic failures cannot be reliably prevented.
For transmission applications, regular fluid and filter changes help keep the valve body clean, which protects hydraulic pressure sensors and manual valves.
Inspecting exposed wiring harnesses for chafing or heat damage can help prevent intermittent circuit faults.
Troubleshooting Tips and Best Practices
Never assume P1713 is a universal temperature or pressure sensor code. Always verify the exact definition for the specific vehicle before purchasing parts.
Do not ignore related codes. A pressure sensor fault may appear alongside other hydraulic circuit codes, while a restricted manual valve fault may appear alongside solenoid switch valve codes.
Check for technical service bulletins applicable to your exact vehicle application, as manufacturers frequently release updated valve bodies or software flashes for recurring transmission faults.

Frequently Asked Questions
Is P1713 a generic or manufacturer-specific code?
No. P1713 is a manufacturer-specific code. Its exact definition varies significantly between automakers, so the factory service information for the specific vehicle must be consulted.
Can I drive my car with a P1713 code?
It depends on the application. If P1713 indicates a restricted manual valve or severe pressure fault, the transmission may unexpectedly shift into neutral or lose gears, making driving unsafe.
Will disconnecting the battery clear the P1713 code?
Disconnecting the battery may temporarily clear the code, but it does not repair the underlying mechanical or electrical fault. The code will return once the module runs its self-test.
Can low transmission fluid cause a P1713 code?
On applications monitoring the transmission fluid temperature or hydraulic pressure, low fluid levels can cause erratic sensor readings or prevent proper valve operation, potentially triggering the fault code.
Does P1713 always mean the sensor is bad?
No. While a failed sensor is a frequent cause on specific applications, the code can also indicate internal valve body wear, a restricted manual valve, or damaged wiring.
What Should You Do About the P1713 Code?
Confirm the exact factory definition and diagnostic procedure for your specific vehicle application. Because P1713 is manufacturer-specific, identifying whether it relates to a hydraulic pressure sensor, a temperature sensor, or a manual valve is mandatory.
Follow the applicable manufacturer diagnostic steps to test the relevant system and components. Once the root cause is confirmed, complete the necessary repairs and verify that the system operates correctly and the code does not return.
