Causes
- Failed EGT sensor (thermocouple or NTC type)
- Open, short, or high-resistance wiring between sensor and PCM
- Corroded, loose, or contaminated connector/pins
- Sensor damaged by soot, oil, ash or excessive heat
- Poor ground or reference at PCM
- Intermittent connection due to broken wire or terminal
Symptoms
- Malfunction Indicator Lamp (MIL) / Check Engine light
- Stored P2082 code (may be one of multiple EGT codes)
- Reduced engine power or limp mode during fault conditions
- Failed or inhibited DPF regeneration on diesel engines
- Poor fuel economy or driveability issues under load
- Intermittent faults or multiple sensor-related codes
What to check
- Read freeze frame and live EGT data with a scan tool; compare Bank 1 vs Bank 2 and sensor 1 vs others
- Inspect EGT sensor, harness and connector for damage, soot, oil or melted insulation
- Backprobe sensor signal and ground while monitoring live data during key on and engine run
- Check connector pins for corrosion, pushed-out terminals or poor mating
- Wiggle test wiring while observing live data to detect intermittent opens/shorts
- Measure wiring continuity and resistance between sensor and PCM; check for short to ground or battery
Signal parameters
- Thermocouple EGT (Type K typical): signal in millivolts. Approx. 0–50 mV across 0–1000°C. Typical operating range under load ~8–30 mV (approx. 200–800°C).
- NTC/Resistance type EGT: resistance falls/rises with temperature. Expect manufacturer-specific resistance table; common values are tens of ohms at high temp and kilo-ohms at ambient — consult spec.
- Voltage-signal sensors (some designs): expect 0–5 V range. Faults often show open (near 0 V or floating) or shorted (near 5 V) or implausible jumps.
- Typical fault indicators: steady out-of-range value, no change with engine temp/load, or rapid noisy fluctuations.
Diagnostic algorithm
- Retrieve freeze-frame and all active/pending EGT and related codes. Note conditions (load, temp, RPM) when code set.
- Visually inspect Bank 2 Sensor 1, its mounting, and wiring harness for heat damage, chafing, contamination or connector issues.
- With a scan tool, monitor live EGT sensor data during key on and while warming or under load. Compare with other EGT sensors and expected behavior.
- Backprobe the sensor connector to measure signal vs. reference ground. For thermocouples measure mV at the sensor connector; for voltage/resistance type measure voltage or resistance per OEM spec.
- Perform continuity and short tests: check continuity from sensor terminal to PCM pin, and check for short to battery or ground. Repair any damaged wiring.
- Wiggle test the harness and connectors while watching live data to find intermittent faults. Repair or replace damaged connectors/terminals.
- If wiring and connector are good, swap with a known-good identical sensor (if available and safe to do) or install a replacement EGT sensor and re-test.
- After repairs, clear codes and perform road test or forced regeneration cycle (if applicable) to confirm the fault does not return.
- If issue persists with good sensor and wiring, check PCM power/ground and consider PCM diagnostic or software update.
Likely causes
- Broken or chafed harness near exhaust flex or mounting points
- Connector contamination/corrosion from moisture or exhaust residue
- Sensor element failed from over-temperature or physical damage
- Short to battery or ground from damaged insulation
- Incorrect sensor installed or incompatible replacement
Fault status
Status
PCM detected Exhaust Gas Temperature Sensor Circuit Range/Performance fault for Bank 2 Sensor 1 — signal outside expected range or inconsistent with other inputs.
Repair difficulty: Medium
Diagnostic time: 0.5 - 2.0 hours
