P0712 on Chevrolet
Transmission Fluid Temperature Sensor Circuit Low Input
P0712 on Chevrolet vehicles indicates transmission fluid temperature sensor circuit low input. Au7o has documented this code across 1 Chevrolet model — most commonly on Silverado 1500. Set when the PCM/TCM reads an abnormally low voltage from the transmission fluid temperature sensor circuit — typically a short to ground — which corresponds to an implausibly high indicated temperature. Typical repair costs on Chevrolet range from $150 to $1,200, depending on the specific model and root cause.
Common Causes of P0712
- •Short to ground in TFT sensor wiring
- •Faulty transmission fluid temperature sensor
- •Corroded/pinched harness
- •Internal transmission wiring fault
- •PCM input fault
P0712 on Chevrolet by Model
Chevrolet Silverado 1500(1 issue)
- Transmission Overheating from Failed 8L90 Thermal Bypass Valve / Cooler-Line Leaks2015-2022
Silverado 1500 trucks with the 8L90 eight-speed (and the older 6L80 six-speed) can run dangerously hot when the factory transmission thermal bypass valve sticks closed, so fluid never reaches the cooler — common under towing or heavy load. Sustained temperatures above ~220-250°F oxidize the fluid and cook the clutches and torque converter, accelerating the separately-known shudder/wear and shortening transmission life. Compounding this, the transmission cooler lines and fittings are a frequent leak point on these trucks, dropping fluid level and worsening heat. Owners towing in hot climates are most affected.
