Code No. P2080: No. 1 Exhaust Gas Temperature Sensor Performance


DIAGNOSIS CONTENT



TROUBLE JUDGMENT


Check Conditions
  • The barometric pressure is above the normal minimum pressure.
  • Examination of the No. 1 exhaust gas temperature sensors on plausibility has not been inhibited.
Judgment Criterion
  • The amount of the difference between the exhaust gas temperature of No. 1 exhaust gas temperature sensor and the exhaust gas temperature of No. 2 exhaust gas temperature sensor, minus the correction value is above the threshold during cold start.

TROUBLE JUDGMENT


Check Conditions
  • The barometric pressure is above the normal minimum pressure.
  • Examination of the No. 1 exhaust gas temperature sensors on plausibility has not been inhibited.
Judgment Criterion
  • The amount of the difference between the intake air temperature and the exhaust gas temperature of No. 1 exhaust gas temperature sensor, minus the correction value is above the threshold during cold start.

PROBABLE CAUSE



  • Failed No. 1 exhaust gas temperature sensor
  • Failed electrical harness in No. 1 exhaust gas temperature sensor circuit
