Code P0712 2018 Chevrolet Silverado Description
The P0712 diagnostic trouble code (DTC) is specific to the transmission fluid temperature sensor circuit in a 2018 Chevrolet Silverado. This code indicates that there is a low voltage condition in the transmission fluid temperature sensor circuit. The transmission fluid temperature sensor is responsible for monitoring the temperature of the transmission fluid and providing this data to the vehicle's engine control module (ECM). The ECM uses this information to adjust shift points and ensure optimal performance and fuel efficiency.
Common Causes of P0712 2018 Chevrolet Silverado
- Faulty Transmission Fluid Temperature Sensor: The sensor itself may be malfunctioning, causing inaccurate voltage readings.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can result in low voltage readings.
- Poor Electrical Connection: A loose or poor connection between the sensor and the ECM can lead to low voltage in the circuit.
- ECM Malfunction: In rare cases, a malfunctioning ECM could be causing the low voltage condition in the transmission fluid temperature sensor circuit.
Symptoms of P0712 2018 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Transmission Shifting Issues: The vehicle may experience erratic or delayed shifting patterns due to inaccurate temperature readings from the sensor.
- Reduced Fuel Efficiency: Improper transmission fluid temperature readings can lead to decreased fuel efficiency as the ECM may not be able to optimize performance.
- Overheating Transmission: In severe cases, the transmission may overheat due to the sensor reporting low temperatures, causing potential damage to internal components.
How to Fix P0712 2018 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scan tool to read the DTC and pinpoint the exact cause of the low voltage condition in the transmission fluid temperature sensor circuit.
- Inspect Sensor and Wiring: Check the sensor for any signs of damage or malfunction, and inspect the wiring for any visible issues.
- Repair or Replace Sensor: If the sensor is faulty, replace it with a new one. Ensure proper installation and connection to the wiring harness.
- Repair Wiring: If the wiring is damaged, repair or replace the affected wires to ensure a secure electrical connection.
- Clear DTC and Test Drive: Clear the DTC from the ECM using a scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0712 2018 Chevrolet Silverado
The typical repair costs for addressing a P0712 code in a 2018 Chevrolet Silverado can vary depending on the extent of the issue and the labor rates in your area. On average, the cost of replacing a transmission fluid temperature sensor ranges from $150 to $250, including parts and labor. Additional costs may apply if wiring repairs or ECM diagnosis is needed. It's recommended to consult with a trusted mechanic or auto repair shop for a more accurate estimate based on your specific situation. Keep in mind that labor rates can vary between different locations and types of repair facilities.

Frequently Asked Questions about P0712 2018 Chevrolet Silverado Code
1. What does the OBDII code P0712 mean on a 2018 Chevrolet Silverado?
P0712 indicates a "Transmission Fluid Temperature Sensor Circuit Low Voltage," meaning the sensor is reporting a voltage signal lower than expected by the transmission control module (TCM).
2. What are the common symptoms of code P0712 in a 2018 Chevrolet Silverado?
Symptoms may include erratic or harsh shifting, the transmission staying in fail-safe mode, poor fuel economy, and an illuminated check engine light.
3. What causes the P0712 code in a 2018 Chevrolet Silverado?
Common causes include a faulty transmission fluid temperature (TFT) sensor, damaged or corroded wiring, poor electrical connections, or low transmission fluid levels.
4. Can low transmission fluid cause the P0712 code on a 2018 Chevrolet Silverado?
Yes, low transmission fluid can affect sensor readings and cause the P0712 code to be triggered.
5. How do you diagnose the P0712 code on a 2018 Chevrolet Silverado?
Diagnosis involves checking the transmission fluid level and condition, inspecting the TFT sensor and wiring for damage, and testing the sensor's voltage and resistance with a multimeter.
6. Can I drive my 2018 Chevrolet Silverado with the P0712 code?
Driving with the P0712 code is not recommended, as it may lead to transmission performance issues or further damage due to incorrect fluid temperature readings.
7. How do you fix the P0712 code on a 2018 Chevrolet Silverado?
Repairs may include replacing the TFT sensor, repairing damaged wiring or connectors, refilling or flushing the transmission fluid, or reprogramming the TCM if necessary.
8. How much does it cost to fix the P0712 code on a 2018 Chevrolet Silverado?
The repair cost can vary, typically ranging from $150 to $400, depending on whether the sensor, wiring, or fluid needs attention.
