P2035Exhaust Gas Temperature Sensor Circuit Low (Bank 2 Sensor 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2035 reports that the signal of temperature sensor 2 on bank 2 has dropped below its plausible floor. Whether that is a short or an open depends on the sensor curve: with a thermistor pulled up by the control unit a grounded wire drags the voltage down, whereas some circuits read near zero when the loop is broken. No manufacturer documents P2035 publicly. Deutz, the one maker found using this sensor slot, keeps the short to ground under P2034-11 instead. The bank 1 counterpart P2032 shows typical limits: GM's 2018 diesels fail below a resistance equivalent of 142 ohms as a Type B code (MIL after two trips). CARB requires such out-of-range checks for every emission-relevant input. Expect the dosing or regeneration strategy that relies on this reading to be cut back.
- What you may notice
- Engine warning lamp on
- Temperature reading on bank 2 implausibly low or at the limit
- Regeneration or DEF dosing limited
- Likely causes
- LikelySignal wire chafed through to ground on the exhaust or frame
- PossibleInternal short in the sensing element
- RareWater bridging the connector pins
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
