P2032 Code - Exhaust Gas Temperature Sensor 2 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) 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 P2032 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.

Code Tech Notes

After starting the engine, the exhaust gas temperature sensor temperature should rise steadily, then stabilize after the engine reaches operating temperature. Exhaust gas temperature sensors may fail intermittently while operating under extreme temperatures. Review the Freeze Frame/Failure Records to verify the failure criteria.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P2032 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 P2032 Code

1. What does the OBDII code P2032 mean?

P2032 indicates that the Exhaust Gas Temperature (EGT) Sensor 2 has detected a circuit low voltage, typically signaling an issue with the sensor or its wiring.

2. What are the symptoms of code P2032?

Common symptoms include reduced fuel efficiency, poor engine performance, an illuminated Check Engine Light, or the engine entering limp mode.

3. What causes the P2032 code?

The most common causes are a faulty EGT sensor, damaged or corroded wiring, a loose electrical connection, or a failure in the engine control module (ECM).

4. Can I drive with the P2032 code?

Driving with this code is possible but not recommended, as it may lead to increased emissions, reduced performance, or damage to the catalytic converter over time.

5. How do I fix the P2032 code?

Repairs may include replacing the EGT sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or, in rare cases, replacing the ECM.

6. How do I diagnose the P2032 code?

Start by inspecting the EGT sensor and its wiring for damage or corrosion, then use a multimeter to check for proper voltage and resistance in the circuit.

7. Where is Exhaust Gas Temperature Sensor 2 located?

Sensor 2 is typically located downstream of the turbocharger or catalytic converter, depending on the vehicle's exhaust system design.

8. What tools are needed to repair the P2032 code?

You may need a diagnostic scanner, a multimeter, and basic hand tools to inspect, test, and replace the EGT sensor or wiring.

9. Can a bad EGT sensor cause other problems?

Yes, a malfunctioning EGT sensor can lead to incorrect exhaust temperature readings, potentially causing engine mismanagement or damage to the catalytic converter.

10. How much does it cost to fix the P2032 code?

Repair costs vary but typically range from $100 to $300, depending on whether the issue is a faulty sensor, wiring, or a more complex problem.
