Generic P — Powertrain

Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 2

Brand: Generic
Type: P — Powertrain
AI status

Page language: EN

Causes

  • Damaged or failed Bank 2 Sensor 2 EGT sensor
  • Short to ground in the sensor signal or heater circuit wiring
  • Open or high-resistance connection (corroded or loose connector/terminal)
  • Wiring harness damage (chafing, melted, pinched)
  • Exhaust leak or heavy contamination on the sensor
  • Faulty ECM/PCM (rare)

Symptoms

  • Check Engine Light (MIL) illuminated
  • Reduced engine power or limp mode on some vehicles
  • Failed emissions test or increased emissions
  • Difficulty with DPF regeneration on diesel vehicles (if equipped)
  • Possible reduced fuel economy or drivability concerns

What to check

  • Retrieve freeze frame and live data for EGT Bank 2 Sensor 2
  • Visual inspection of sensor, connector, and harness for heat damage, corrosion, or physical damage
  • Backprobe sensor signal and ground with key on and engine running to observe voltage/temperature values
  • Measure resistance or millivolt output of the sensor per vehicle spec (engine cold and hot as applicable)
  • Check for continuity from harness connector to PCM and for shorts to ground or battery
  • Wiggle test wiring while monitoring live data to reproduce fault

Signal parameters

  • Typical sensor signal range: 0–5 V (varies by design); low-circuit fault often indicated by
  • Heater circuit (if present): reference supply ≈ battery voltage with key ON; heater resistance varies by sensor (check OEM spec)
  • Expected temperature-related voltage or millivolt output should increase with exhaust temperature; verify with live data during warm-up
  • Short to ground will pull the signal toward 0 V; open circuit may show no signal or fixed low value

Diagnostic algorithm

  1. Read and record stored codes, freeze-frame and live EGT data for Bank 2 Sensor 2. Note engine conditions when the fault set.
  2. Perform a visual inspection of sensor, exhaust near sensor, connector and wiring for damage, melted insulation, or corrosion. Repair obvious damage.
  3. With engine OFF and cooled, disconnect sensor connector and inspect pins for corrosion or bent pins. Reconnect securely.
  4. Backprobe the sensor harness connector with key ON (engine OFF) and measure reference voltage and ground continuity. Compare to OEM values.
  5. Start engine (or run to safe idle) and monitor live EGT signal. If signal is abnormally low, perform a wiggle test on harness and connectors while watching data.
  6. Check continuity from the sensor signal and heater wires to the PCM connector. Check for short to ground on the signal wire (infinite or very low resistance to ground indicates short).
  7. If equipped with a heater, verify heater supply voltage and measure heater resistance at the sensor; compare to spec. A shorted heater can affect signal or set separate heater codes.
  8. If wiring and connectors are good, substitute a known-good EGT sensor (if available) or install a new sensor and re-test.
  9. Clear codes and road-test to verify the code does not return. If code returns and wiring checks are good, consider PCM diagnosis or replacement as a last resort.
  10. Safety note: Exhaust components and sensors become very hot. Allow components to cool before handling and use appropriate PPE.

Likely causes

  • Corroded connector or water ingress at the sensor harness
  • Frayed or chafed wiring shorting to chassis ground near the sensor
  • Failed sensor element or internal short in sensor heater
  • Recent work near the exhaust that disturbed wiring or connectors

Fault status

⚠️ Status
P2035 — Exhaust Gas Temperature Sensor Circuit Low (Bank 2, Sensor 2): PCM detected a low-voltage or low-circuit condition from the downstream EGT sensor on bank 2. Inspect sensor, harness, and connections for shorts, opens or damage.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
