P2087Exhaust Gas Temperature Sensor Circuit Intermittent (Bank 2 Sensor 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2087 is reserved for a bank 2 sensor 2 exhaust temperature signal that is erratic or drops out. No manufacturer publishes it; we checked GM, Ford, VW, Deutz and the NHTSA bulletin index without a hit, and Ford's 2014 petrol list leaves it out. For a monitor in this style, GM's bank 1 counterpart P2085 is the reference: in table 18OBDG04 it counts resistance steps above 10 ohms between samples taken every 100 ms and sets a Type B code at 20 out of 40. CARB requires that intermittent faults of emission-relevant inputs be detected. If the code ever appears, the sensor connector and the lead along the second exhaust pipe are the first things to inspect. P2086 covers a steady but implausible value from the same sensor, P2034–P2036 its hard electrical faults.
