Causes
- Open or shorted wiring in EGT sensor signal or heater circuit
- Corroded, loose or damaged connector at the EGT sensor
- Failed EGT sensor (thermistor, thermocouple, or integrated sensor/heater)
- Short to battery voltage on the sensor signal or heater feed
- Exhaust leak, soot contamination, or physical damage to the sensor element
- Faulty PCM/ECM or poor ground at the module (rare)
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated
- Stored P2036 diagnostic trouble code (may be accompanied by related EGT codes)
- Possible reduced engine power or limp mode if the PCM limits operation for protection
- Inhibited or failed diesel particulate filter (DPF) active regeneration or abnormal regeneration behavior
- Reduced fuel economy or increased emissions
- Visible soot or damage at sensor location (on inspection)
What to check
- Verify freeze frame and pending codes; note operating conditions when code set (load, rpm, temperature)
- Visually inspect EGT sensor (Bank 2 Sensor 2) and connector for heat damage, soot, contamination, or physical damage
- Check connector pins for corrosion, bent pins, or pushed-out terminals and secure mating
- Inspect wiring harness along exhaust route for chafing, heat damage, or exposed conductors
- With ignition off and exhaust cool, gently wiggle wiring while observing for intermittent faults (use scan tool live data)
- Backprobe sensor connector and measure signal voltage and heater feed with key on / engine off and during commanded heater on (if applicable)
Signal parameters
- Sensor type: may be thermistor, thermocouple (mV output), or voltage-type EGT sensor depending on application — consult service data
- Typical signal line voltage range (voltage-type): ~0–5.0 V; ‘High’ condition often >4.5 V (varies by manufacturer)
- Thermocouple type: low mV at ambient (single-digit mV), rising with temperature; look for increasing mV with heat
- Thermistor type: resistance decreases or increases with temperature depending on design; verify resistance vs temperature curve from service data
- Heater circuit: supply typically switched/pulsed by PCM (0–12 V) when commanded; measure for proper supply and ground and presence of PWM while the heater is commanded on
- Expected behavior: signal should move smoothly with temperature; abrupt high/rail voltages or fixed high values indicate circuit fault
Diagnostic algorithm
- Obtain the freeze frame and complete diagnostic trouble code list; note whether the condition is intermittent or constant.
- Safety: allow exhaust and sensor to cool before probing or removing sensor; use heat-resistant gloves when required.
- Perform a visual inspection of the sensor, connector and wiring for obvious damage, corrosion, soot buildup or signs of overheating. Repair any damage found and clear codes to test.
- Check connector continuity: disconnect sensor, check for corrosion and proper terminal fit. Clean or repair connector as needed.
- Measure supply voltage at the sensor connector (with ignition on) — verify PCM controlled heater feed and reference voltages per service data. Look for a short to battery if voltage is higher than expected.
- Backprobe the signal wire with the engine cold and then with the exhaust heated (or warm the sensor with a heat gun) while monitoring live data or voltage/millivolt output. Confirm the signal increases appropriately with temperature. If signal is stuck at a high value or rail, suspect wiring or sensor failure.
- If applicable, check sensor element resistance (thermistor) at ambient and while heating; compare curve to specification. For thermocouple sensors measure mV output while heating — it should rise progressively.
- Inspect and test heater circuit: command the heater on with a scan tool, verify PCM command and measure voltage/current to the heater. If heater is commanded but not drawing current or drawing too much, suspect open/short or failed heater.
- Perform wiggle tests on harness while monitoring signal for intermittent faults. Repair any chafed or broken wires and re-test.
- If wiring, connectors, and PCM outputs are good, replace the EGT sensor. Use OEM or specified replacement to avoid calibration mismatches.
- After repairs, clear codes, perform a relevant drive cycle or forced regen (if applicable) and verify code does not return; re-check live data to confirm normal sensor behavior.
- If code persists after replacement and wiring checks, consider PCM or harness ground diagnosis and consult manufacturer technical resources or TSBs.
Likely causes
- Wiring shorted to 12V on the sensor signal or heater feed
- Sensor element failed internally and reporting high temperature/voltage
- Connector pins corroded or pushed out causing intermittent high reading
- Heater control circuit stuck on causing over-temperature reading or circuit over-voltage
- Exhaust soot or debris causing sensor to read incorrectly
Fault status
Status
Exhaust Gas Temperature Sensor Circuit High – Bank 2 Sensor 2. The EGT sensor signal is reporting a higher-than-expected value or voltage on Bank 2, Sensor 2, indicating a possible sensor or circuit fault.
Repair difficulty: Medium
Diagnostic time: 1.5-3.0 hours
