P2033 2014 Chevrolet Silverado Code - Exhaust Gas Temperature Sensor 2 Circuit High 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) 2, Exhaust Gas Temperature Sensor 2 harness is open or shorted, Exhaust Gas Temperature Sensor 2 circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P2033 2014 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 greater than 900 Ω for greater than 2 s.

Frequently Asked Questions about P2033 2014 Chevrolet Silverado Code

1. What does the OBDII code P2033 mean on a 2014 Chevrolet Silverado?

P2033 indicates a high voltage issue in the Exhaust Gas Temperature (EGT) Sensor 2 circuit, which monitors exhaust temperatures to protect components and ensure proper emissions control.

2. What are the symptoms of code P2033 on a 2014 Chevrolet Silverado?

Common symptoms include an illuminated check engine light, reduced fuel efficiency, potential limp mode, and in some cases, excessive exhaust emissions.

3. What causes the P2033 code on a 2014 Chevrolet Silverado?

Possible causes include a faulty EGT sensor, damaged wiring or connectors, an open or short in the sensor circuit, or an issue with the engine control module (ECM).

4. Can I drive my 2014 Chevrolet Silverado with a P2033 code?

Driving with a P2033 code is not recommended, as it may lead to increased emissions, reduced performance, or damage to exhaust components such as the catalytic converter.

5. How do I diagnose the P2033 code on a 2014 Chevrolet Silverado?

Diagnosis involves checking the EGT sensor for damage, inspecting the wiring and connectors for corrosion or breaks, and using a multimeter to test the sensor's voltage and resistance.

6. How do I fix the P2033 code on my 2014 Chevrolet Silverado?

Repairs may include replacing the faulty EGT sensor, repairing or replacing damaged wiring or connectors, and, in rare cases, reprogramming or replacing the ECM.

7. How much does it cost to fix code P2033 on a 2014 Chevrolet Silverado?

The repair cost varies, but replacing the EGT sensor typically costs $100â€“$300, including parts and labor. Wiring repairs may add to the cost.

8. Where is the Exhaust Gas Temperature Sensor 2 located on a 2014 Chevrolet Silverado?

Sensor 2 is typically located downstream in the exhaust system, after the diesel particulate filter (DPF) or catalytic converter, depending on the engine configuration.

9. Can a bad EGT sensor damage my 2014 Chevrolet Silverado?

Yes, a malfunctioning EGT sensor can cause improper exhaust temperature readings, which may lead to overheating of exhaust components and potential damage to the catalytic converter or DPF.

10. Does clearing the P2033 code fix the problem on a 2014 Chevrolet Silverado?

Clearing the code without addressing the underlying issue will not fix the problem, and the code is likely to reappear until the root cause is resolved.
