Code P0653 2017 Chevrolet Silverado Description

The Engine Control Module (ECM) has four (4) internal 5 Volt reference circuits (Some models have two (2) internal 5 Volt reference circuits). Each internal reference circuit provides external 5 Volt reference circuits for more than one sensor. A short to ground or short to voltage on one external 5 Volt reference circuit can affect all the components connected to the same internal 5 Volt reference circuit. The Diagnostic Trouble Code (DTC) will be set when the ECM detects a short to voltage or ground on any of the 5 Volt reference circuits for greater than 0.5 s.

Code Tech Notes

Disconnecting one component at a time from the affected 5 Volt reference circuit while observing the scan tool 5 Volt Reference Circuit Status parameter may help locate the fault. The scan tool parameter will change from Malfunction to OK when the source of the fault is disconnected. If all 5 Volt reference components have been disconnected and a fault is still indicated, the fault may exist in the wiring harness.

The 5 Volt reference 2 circuit provides 5 Volt to the following sensors: (Some models may have different sensors, please consult the factory service manual for the list of sensors for your model and year)

- Brake pedal position sensor
- Crankshaft position sensor

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P0653 2017 Chevrolet Silverado code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0653 2017 Chevrolet Silverado Code

What does the OBDII code P0653 mean on a 2017 Chevrolet Silverado?

P0653 indicates a "5 Volt Reference 2 Circuit High Voltage" issue, meaning the voltage in the second reference circuit is higher than the expected range.

What are the common symptoms of a P0653 code in a 2017 Chevrolet Silverado?

Symptoms may include the check engine light turning on, poor engine performance, erratic transmission behavior, or malfunctioning sensors connected to the 5V reference circuit.

What causes the P0653 code to appear on a 2017 Chevrolet Silverado?

Possible causes include a short to voltage in the 5V reference circuit, a faulty sensor, damaged wiring, a defective ECM (engine control module), or corrosion on connectors.

How do I diagnose the P0653 code in my 2017 Chevrolet Silverado?

Start by using a scan tool to confirm the code, inspect the wiring and connectors in the 5V reference circuit for damage or corrosion, and test the sensors connected to the circuit for proper operation.

Can a faulty ECM cause the P0653 code?

Yes, a defective ECM can sometimes cause this code if it fails to regulate the 5V reference properly.

Is it safe to drive my 2017 Chevrolet Silverado with a P0653 code?

Driving with a P0653 code is not recommended, as it may affect engine performance and other critical systems, potentially leading to further damage.

How is the P0653 code fixed on a 2017 Chevrolet Silverado?

Repairs may include fixing or replacing damaged wiring, cleaning corroded connectors, replacing a faulty sensor, or reprogramming or replacing the ECM if necessary.

Which sensors are typically affected by the P0653 code in a 2017 Chevrolet Silverado?

Sensors that rely on the 5V reference circuit, such as the throttle position sensor (TPS), manifold absolute pressure (MAP) sensor, or fuel pressure sensor, may be affected.

How much does it cost to repair a P0653 code on a 2017 Chevrolet Silverado?

Repair costs vary depending on the issue, but fixing damaged wiring or replacing a sensor could range from $50 to $300, while an ECM replacement may cost $500 or more.

Can clearing the P0653 code fix the problem?

Clearing the code may temporarily turn off the check engine light, but the issue will likely return unless the underlying cause is addressed.
