Fix P2036: STEP-BY-STEP diagnostic GUIDE!

The P2036: Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 2 code indicates that the exhaust gas temperature (EGT) sensor on Bank 2 (Sensor 2) is reporting higher than expected voltage. This could be due to a faulty sensor, wiring problems, or issues within the sensor’s circuit.

P2036 – Quick Overview

CodeInformation
MeaningP2036: Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 2
Is it serious?Yes, high voltage in the EGT sensor circuit can lead to incorrect exhaust temperature readings, which may result in poor emissions control or damage to components like the catalytic converter and DPF.
Possible causes– High voltage in the sensor circuit
– Faulty sensor
– Wiring or connector issues
How to diagnose?– Measure voltage in the sensor circuit
– Test the sensor
– Inspect wiring and connectors

P2036 Meaning

The P2036: Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 2 code means that the EGT sensor on Bank 2 (the side opposite Bank 1) is reading higher than expected voltage. The EGT sensor is essential for monitoring exhaust temperatures and protecting critical components like the catalytic converter and diesel particulate filter (DPF). High voltage could indicate a malfunctioning sensor or wiring issues affecting the readings.

Step-by-step diagnostic guide

ActionDescriptionTools Needed
Check for Other CodesUse an OBD-II scanner to check for additional codes related to the exhaust system or emissions components. These may provide more context for diagnosing the issue.OBD-II Scanner
Measure Voltage in the Sensor CircuitUse a multimeter to measure the voltage in the EGT sensor circuit for Bank 2 Sensor 2. Compare the readings to the manufacturer’s specifications to confirm if the voltage is too high.Multimeter
Test the Exhaust Gas Temperature SensorUse a diagnostic tool to test the EGT sensor’s resistance and output. If the sensor is providing incorrect readings, it may be faulty and require replacement.Multimeter, Diagnostic Tool
Inspect Wiring and ConnectorsVisually inspect the wiring and connectors leading to the EGT sensor for signs of damage, corrosion, or loose connections that could cause high voltage in the circuit.Flashlight, Multimeter
Check Circuit ContinuityPerform a continuity test on the wiring connected to the EGT sensor to check for shorts, breaks, or high resistance that could be causing the high voltage issue.Multimeter
Inspect the Exhaust SystemInspect the exhaust system near the sensor for leaks, blockages, or damage that could affect the sensor’s performance or cause the sensor to overheat and generate higher readings.Flashlight, Exhaust Cleaner
Replace the Exhaust Gas Temperature SensorIf the EGT sensor is determined to be faulty, replace it with a new one. Ensure the sensor is correctly installed to avoid future issues.Replacement EGT Sensor, Wrench
Repair or Replace Damaged WiringRepair or replace any damaged wiring, connectors, or faulty components related to the EGT sensor circuit to restore proper voltage levels and functionality.Wiring Repair Kit
Clear the Code and Test DriveAfter completing the repairs, clear the P2036 code using an OBD-II scanner. Take the vehicle for a test drive to ensure that the sensor is operating correctly and the issue is resolved.OBD-II Scanner, Vehicle Owner’s Manual
Recheck for CodesAfter the test drive, re-scan the vehicle to verify that the P2036 code has been cleared and has not returned.OBD-II Scanner
