Code P06AC 2015 Chevrolet Silverado Description
The P06AC diagnostic trouble code (DTC) for a 2015 Chevrolet Silverado indicates an issue with the Control Module Power Up Temperature Sensor Performance. This code is specifically related to the temperature sensor within the vehicle's control module, which is responsible for monitoring the temperature of the module during power-up sequences. If the sensor detects that the temperature is outside of the expected range or if it is not functioning properly, it will trigger this code.
Common Causes of P06AC 2015 Chevrolet Silverado
- Faulty Temperature Sensor: The most common cause of the P06AC code is a malfunctioning temperature sensor within the control module.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the temperature sensor can also trigger this code.
- Control Module Malfunction: If the control module itself is faulty, it may not be able to receive accurate temperature readings from the sensor.
- Software Glitch: Occasionally, a software glitch within the control module can cause erroneous temperature readings, leading to the P06AC code.
Symptoms of P06AC 2015 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P06AC code is the illumination of the Check Engine Light on the dashboard.
- Reduced Fuel Efficiency: The vehicle may experience decreased fuel efficiency due to incorrect temperature readings affecting fuel mixture.
- Rough Idle: The engine may idle roughly or inconsistently due to improper temperature sensor readings impacting ignition timing.
- Engine Stalling: In severe cases, the engine may stall or have difficulty starting due to incorrect temperature data affecting crucial operating parameters.
How to Fix P06AC 2015 Chevrolet Silverado
- Diagnose: Use a diagnostic scanner to retrieve the DTC and pinpoint the source of the issue, whether it is the temperature sensor, wiring, or control module.
- Inspect Wiring: Check the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
- Replace Temperature Sensor: If the temperature sensor is determined to be faulty, replace it with a new sensor that meets the manufacturer's specifications.
- Reset Control Module: Clear the DTC from the control module and reset it to ensure that the issue has been resolved.
- Test Drive: After repairing the issue, perform a test drive to ensure that the Check Engine Light does not reappear and that the vehicle's performance has returned to normal.

Frequently Asked Questions about P06AC 2015 Chevrolet Silverado Code
1. What does the P06AC code mean on a 2015 Chevrolet Silverado?
The P06AC code indicates an issue with the Control Module Power Up Temperature Sensor Performance, meaning the powertrain control module (PCM) has detected an abnormal signal from the temperature sensor during startup.
2. What are the common symptoms of the P06AC code?
Common symptoms include an illuminated check engine light, potential starting issues, poor engine performance, or no noticeable symptoms in some cases.
3. What causes the P06AC code to appear?
Possible causes include a faulty temperature sensor, damaged wiring or connectors, a malfunctioning PCM, or incorrect sensor calibration.
4. Can I drive my 2015 Chevrolet Silverado with the P06AC code?
While the truck may still drive, ignoring the code could lead to reduced performance or further damage. It’s best to address the issue promptly.
5. How do I diagnose the P06AC code on my Silverado?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the temperature sensor and wiring, and testing the sensor’s resistance or signal with a multimeter.
6. How do I fix the P06AC code on a 2015 Chevrolet Silverado?
Repairs may include replacing the faulty temperature sensor, repairing damaged wiring, cleaning or reseating connectors, or reprogramming/updating the PCM.
7. How much does it cost to repair the P06AC code issue?
Repair costs vary, but replacing a temperature sensor typically costs $100–$300, including labor. PCM repairs or updates may cost more.
