What are the symptoms of a bad exhaust temperature sensor?

2026-07-14

A faulty exhaust temperature sensor will trigger a series of obvious vehicle symptoms, which are mainly manifested in the following aspects:

  1. ‌Dashboard warning lights‌
    The glow plug system warning light flashes, the particulate filter warning light and the engine control malfunction indicator light will turn on abnormally.
  2. ‌Abnormal driving performance‌
    The vehicle will experience poor acceleration, hesitation, rough idle, or even stalling, and the power output will decrease significantly due to incorrect judgment of the particulate filter saturation.
  3. ‌Increased fuel consumption‌
    The particulate filter regeneration cycle will be prolonged, which leads to a significant rise in fuel consumption.
  4. ‌Excessive exhaust emissions‌
    The content of CO, NOx and HC in the exhaust gas will increase, and black smoke may be emitted from the exhaust pipe.
  5. ‌Abnormal regeneration‌
    The active DPF regeneration process will be forced to abort, which further aggravates the above faults.
