P245D 2014 Chevrolet Silverado Code - Exhaust Gas Recirculation Cooler Bypass Control Circuit High Voltage

Quick Answer

The Engine Control Module (ECM) uses the Exhaust Gas Recirculation (EGR) bypass valve position sensor to determine the position of the bypass valve. Common causes include Faulty Exhaust Gas Recirculation (EGR) Cooler Bypass Valve, Exhaust Gas Recirculation Cooler Bypass Valve harness is open or shorted, Exhaust Gas Recirculation Cooler Bypass Valve circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

What it means: P245D 2014 Chevrolet Silverado indicates Exhaust Gas Recirculation Cooler Bypass Control Circuit High Voltage.
Common causes: Common causes include Faulty Exhaust Gas Recirculation (EGR) Cooler Bypass Valve, Exhaust Gas Recirculation Cooler Bypass Valve harness is open or shorted, Exhaust Gas Recirculation Cooler Bypass Valve circuit poor electrical connection.
Severity: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P245D 2014 Chevrolet Silverado Description

The Engine Control Module (ECM) uses the Exhaust Gas Recirculation (EGR) bypass valve position sensor to determine the position of the bypass valve. The ECM sends a reference voltage through the 5-volt reference circuit to the position sensor. The ECM provides a voltage return path for the sensor through the low reference circuit. A variable voltage signal, based on the valve position, is sent from the sensor to the ECM through the position sensor signal circuit. The ECM compares the actual bypass valve position with the desired bypass valve position when the valve is commanded open or closed. The EGR cooler bypass valve is controlled by the ECM through the bypass valve motor high control and the low control circuits. The ECM will pulse width modulate the low control circuit to ground when EGR cooler bypass is desired.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the EGR cooler bypass valve control circuits are shorted to voltage for greater than 3 s.

Frequently Asked Questions about P245D 2014 Chevrolet Silverado Code

1. What are the common symptoms of OBDII code P245D in a 2014 Chevrolet Silverado?

The common symptoms include reduced engine performance, rough idling, decreased fuel efficiency, and the illumination of the check engine light.

2. What does the OBDII code P245D "Exhaust Gas Recirculation Cooler Bypass Control Circuit High Voltage" mean for a 2014 Chevrolet Silverado?

This code indicates that the exhaust gas recirculation (EGR) cooler bypass control circuit is detecting a higher than normal voltage, possibly leading to malfunction.

3. What are the possible causes of OBDII code P245D in a 2014 Chevrolet Silverado?

Potential causes include a faulty EGR cooler bypass control solenoid, damaged wiring or connectors in the circuit, a malfunctioning EGR system, or issues with the engine control module.

4. How can I diagnose the OBDII code P245D in my 2014 Chevrolet Silverado?

Diagnosis typically involves using a diagnostic scanner to retrieve the trouble codes, inspecting the EGR system components, checking the wiring and connectors for any damage, and performing voltage tests on the EGR cooler bypass control circuit.

5. Is it safe to continue driving my 2014 Chevrolet Silverado with the P245D code?

It is not recommended to drive the vehicle extensively with this code present, as it can lead to reduced engine performance and potentially cause further damage to the EGR system components.

6. Can I repair OBDII code P245D in my 2014 Chevrolet Silverado myself?

While some DIY enthusiasts may attempt to address this issue, it is recommended to consult a professional mechanic with experience in diagnosing and repairing EGR system-related faults to ensure proper resolution.

7. What are the repair options for OBDII code P245D in a 2014 Chevrolet Silverado?

Repair options may include replacing the EGR cooler bypass control solenoid, repairing or replacing damaged wiring or connectors, addressing any issues with the EGR system, or reprogramming the engine control module.

8. How much does it typically cost to fix OBDII code P245D in a 2014 Chevrolet Silverado?

Costs can vary depending on the specific repairs needed, parts required, and labor rates in your area. It's advisable to obtain quotes from reputable mechanics or dealerships for an accurate estimate.

9. Can a dirty EGR system cause OBDII code P245D in a 2014 Chevrolet Silverado?

A dirty or clogged EGR system can potentially contribute to issues that trigger this code, but the root cause is usually related to the bypass control circuit, solenoid, or wiring.

10. Will resetting the check engine light make OBDII code P245D disappear in a 2014 Chevrolet Silverado?

Resetting the check engine light may temporarily clear the code, but if the underlying issue triggering the P245D code is not addressed and repaired, the code is likely to reappear upon subsequent engine cycles.
