P2470 2015 Chevrolet Silverado Code - Exhaust Gas Temperature Sensor 4 Circuit Low Voltage

Quick Answer

The Exhaust Gas Temperature sensors (EGTS) are variable resistors that measure the temperature of the exhaust gas. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) 4, Exhaust Gas Temperature Sensor 4 harness is open or shorted, Exhaust Gas Temperature Sensor 4 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.

Code P2470 2015 Chevrolet Silverado Description

The Exhaust Gas Temperature sensors (EGTS) are variable resistors that measure the temperature of the exhaust gas. Exhaust temperature sensor 1 is the first exhaust temperature sensor in the exhaust system, the following exhaust temperature sensors are counted upward from the engine outlet to the exhaust system end. The Engine Control Module (ECM) supplies 5 V to the exhaust gas temperature signal circuit and supplies a ground to the low reference circuit. The exhaust gas temperature sensor temperature information is used by the ECM during the exhaust gas particulate filter cleaning process. The Diagnostic Trouble Code (DTC) will ve set when the ECM detects that the exhaust gas temperature sensor is less than 158 Ω for greater than 2 s.

Frequently Asked Questions about P2470 2015 Chevrolet Silverado Code

1. What does the P2470 code mean on a 2015 Chevrolet Silverado?

The P2470 code indicates a "Exhaust Gas Temperature Sensor 4 Circuit Low Voltage," meaning the sensor is reporting a voltage level below the expected range.

2. What are the symptoms of the P2470 code on a Chevy Silverado?

Common symptoms include the check engine light turning on, reduced engine performance, decreased fuel efficiency, or issues with the vehicleâ€™s emissions system.

3. What causes the P2470 code to appear?

The most common causes are a faulty exhaust gas temperature (EGT) sensor, damaged wiring or connectors, soot buildup on the sensor, or an issue with the vehicle's PCM (Powertrain Control Module).

4. Can I drive my 2015 Silverado with the P2470 code?

While the vehicle may still be drivable, ignoring the issue can lead to further damage to the emissions system or reduced engine efficiency. Itâ€™s best to address the problem promptly.

5. How do I troubleshoot the P2470 code?

Start by inspecting the wiring and connectors for damage or corrosion. Then test the exhaust gas temperature sensor with a multimeter to check for proper operation.

6. How much does it cost to fix the P2470 code on a Chevrolet Silverado?

Repair costs can range from $150 to $300, depending on whether the exhaust gas temperature sensor needs replacement or if there are wiring issues that require attention.

7. Where is Exhaust Gas Temperature Sensor 4 located on a 2015 Silverado?

Sensor 4 is typically located downstream in the exhaust system, near or after the diesel particulate filter (DPF).

8. Can a bad exhaust gas temperature sensor cause damage to the vehicle?

Yes, a faulty sensor can cause improper operation of the emissions system, which could lead to damage to the DPF or catalytic converter over time.

9. How do I clear the P2470 code after repairs?

Once repairs are complete, you can clear the code using an OBDII scanner to reset the check engine light. Make sure the issue is fully resolved to prevent the code from returning.

10. What tools are needed to diagnose the P2470 code?

Youâ€™ll need an OBDII scanner, a multimeter for testing the sensor and wiring, and possibly a repair manual for your 2015 Chevrolet Silverado to locate components.
