Frequently Asked Questions about P0652 2016 Chevrolet Silverado Code
What does the OBDII code P0652 mean on a 2016 Chevrolet Silverado?
P0652 indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the 5-volt reference 2 circuit, which supplies voltage to certain engine sensors.
What are the common symptoms of the P0652 code?
Symptoms may include the Check Engine Light, poor engine performance, reduced fuel efficiency, rough idling, and potential failure of sensors dependent on the 5-volt reference 2 circuit.
What causes the P0652 code to trigger?
Common causes include a short to ground in the wiring, a faulty sensor on the 5-volt reference 2 circuit, a damaged PCM, or corroded electrical connections.
Which sensors are typically affected by the 5-volt reference 2 circuit?
Sensors such as the throttle position sensor (TPS), manifold absolute pressure (MAP) sensor, and other engine-related sensors may depend on the 5-volt reference 2 circuit.
How do you diagnose the P0652 code?
Diagnosis involves using a multimeter to check for proper 5-volt output, inspecting wiring and connectors for damage or shorts, and testing individual sensors connected to the 5-volt reference 2 circuit.
Can a faulty PCM cause the P0652 code?
Yes, a malfunctioning PCM can cause the P0652 code, but this is less common and should only be considered after ruling out wiring and sensor issues.
What should you inspect first when troubleshooting this code?
Start by inspecting the wiring and connectors for the 5-volt reference 2 circuit for damage, corrosion, or shorts to ground.
Is it safe to drive with the P0652 code?
Driving with this code is not recommended, as it can lead to poor engine performance and potentially cause further damage to the vehicle's electrical system or sensors.
How do you fix the P0652 code?
Repairs may include replacing damaged wiring, repairing faulty connectors, replacing a defective sensor, or in rare cases, reprogramming or replacing the PCM.
How much does it cost to repair a P0652 code?
Repair costs vary depending on the issue. Fixing damaged wiring or a connector may cost $50-$150, while replacing a sensor or PCM can range from $200 to $1,200.
