P0713 on Audi
Transmission Fluid Temperature Sensor A Circuit High Input
P0713 on Audi vehicles indicates transmission fluid temperature sensor a circuit high input. Au7o has documented this code across 2 Audi models — most commonly on A3, TT. This code means the transmission computer detected an abnormally high voltage from the transmission fluid temperature (TFT) sensor, which usually corresponds to an open circuit or a sensor reading an unrealistically cold temperature. The TFT sensor lets the controller adapt shift timing and torque converter lockup based on fluid temperature. A bad reading can cause harsh or delayed shifts and may default the transmission to a protective mode.
Common Causes of P0713
- •Faulty transmission fluid temperature sensor
- •Open circuit in the sensor wiring
- •Corroded or loose internal transmission connector
- •Low transmission fluid level
- •Internal harness damage inside the transmission
- •TCM/PCM circuit fault
P0713 on Audi by Model
Audi A3(1 issue)
- Recall 09V333000: DSG Temperature Sensor Wiring Can Drop the A3 Into Neutral2009-2010
If your Audi A3 is a 2009 or 2010 model built with the DSG dual-clutch automatic, it may fall under NHTSA recall 09V333000. The defect is in the wiring harness for a temperature sensor inside the gearbox: some connector wires were insufficiently crimped at the factory. That weak crimp can cause the sensor to falsely detect high gearbox oil temperature, and the transmission protects itself by abruptly shifting to neutral. The driver's first clue is the selector lever position indicator flashing in the instrument panel along with the "depress brake pedal" warning light, which prompts the driver to apply the brake. NHTSA's stated consequence is blunt — an abrupt shift to neutral could lead to a crash without warning, since drive can be lost mid-manoeuvre. Affected cars were manufactured between September 2008 and August 2009. About 16,000 vehicles were covered campaign-wide across all models included, a figure that spans the whole recall rather than the A3 specifically.
Audi TT(1 issue)
- DSG Temperature-Sensor Wiring Can Trigger an Abrupt Shift to Neutral (Recall 09V333)2009
On affected 2009 TT direct-shift gearboxes, insufficiently crimped temperature-sensor wires can falsely report high oil temperature and cause the transmission to shift abruptly into neutral.

What does P0713 mean on Audi?▼
P0713 stands for "Transmission Fluid Temperature Sensor A Circuit High Input." This code means the transmission computer detected an abnormally high voltage from the transmission fluid temperature (TFT) sensor, which usually corresponds to an open circuit or a sensor reading an unrealistically cold temperature. The TFT sensor lets the controller adapt shift timing and torque converter lockup based on fluid temperature. A bad reading can cause harsh or delayed shifts and may default the transmission to a protective mode. On Audi specifically, this code is documented across 2 models.
