P2036Exhaust Gas Temperature Sensor Circuit High (Bank 2 Sensor 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2036 is set when the bank 2, sensor 2 temperature signal climbs above the top of its valid window. On the usual pull-up input that is what an unplugged connector, a broken lead or an element gone open after heat cycling produces, while a short to supply voltage gives the same picture. No manufacturer documents P2036 publicly; Deutz files the short to battery of its second SCR inlet sensor as P2034-12, and GM's 2018 diesel tables carry all their sensors on bank 1. For the bank 1 code P2033 GM's 2018 diesel tables use a resistance equivalent above 922 ohms, confirmed by 10 failed samples, Type B. Because a dead sensor looks like an extremely hot exhaust here, the control unit may also trigger protective power reduction until the circuit is repaired.
- What you may notice
- Engine warning lamp on
- Bank 2 temperature shows an implausibly high value
- Possible protective power reduction
- Likely causes
- LikelySensing element open after repeated heat cycles
- PossibleConnector unplugged, loose or with pushed-back terminal
- PossibleSensor lead broken near the hot exhaust
- RareSignal wire shorted to supply voltage
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €60 – €350
