Code P182B 2016 GMC Sierra Description
The P182B diagnostic trouble code (DTC) for a 2016 GMC Sierra refers to an issue with the Internal Mode Switch 'B' Circuit Low Voltage. The Internal Mode Switch (IMS) is a component within the transmission control module (TCM) that helps the vehicle's computer system determine the current gear selection. In this case, the 'B' circuit is reporting low voltage, indicating a potential problem with the electrical signal being sent from the IMS to the TCM.
Common Causes of P182B 2016 GMC Sierra
- Faulty Internal Mode Switch (IMS)
- Damaged wiring or connectors in the IMS circuit
- Malfunctioning Transmission Control Module (TCM)
- Low battery voltage affecting electrical system
- Corrosion or moisture in the electrical connections
Symptoms of P182B 2016 GMC Sierra
- Harsh shifting between gears
- Delayed engagement when shifting
- Slipping gears during acceleration
- Transmission overheating
- Illumination of the Check Engine Light
How to Fix P182B 2016 GMC Sierra
- Begin by conducting a thorough inspection of the IMS, wiring, and connectors for any visible damage or corrosion.
- Test the voltage output of the IMS 'B' circuit using a multimeter to determine if it is within the specified range.
- If the voltage is low, replace the Internal Mode Switch and clear the DTC from the vehicle's computer system.
- Check and repair any damaged wiring or connectors in the circuit.
- Perform a test drive to ensure the transmission shifts smoothly and accurately after the repair.
Cost to Fix P182B 2016 GMC Sierra
The typical repair costs for addressing the Internal Mode Switch 'B' Circuit Low Voltage issue can range from $200 to $500, including parts and labor.
