MR507784 Mitsubishi SENSOR,EXHAUST HIGH TEMP, Price: 149.69$, Weight: 0.14kg

Exhaust High Temperature Sensor

This exhaust heat sensor is a key safety and performance part in the exhaust line. It measures very high exhaust gas temperature and sends a live signal to the engine/hybrid control unit. That information helps the system protect the catalytic converter, turbo components (when equipped), and nearby wiring/heat shields from overheating ?.

Why this part is needed

Modern Mitsubishi systems run tight emissions and thermal limits. When exhaust temperature rises under load, regeneration, or hard acceleration, the control unit uses this sensor to adjust fueling, ignition timing, and protection strategies to keep temperatures in the safe zone.

How it works

The sensor sits in the exhaust stream and converts heat into an electrical value. The ECU reads it instantly, then commands cooling actions such as mixture correction, power limiting, or warning logic. This keeps exhaust after-treatment working efficiently ✅.

What happens if it’s faulty

If the sensor is broken or drifting, you may see a check engine light, reduced power (limp mode), poor fuel economy, strong exhaust smell, failed emissions test, or overheating damage to the catalyst and surrounding parts. In worst cases, excessive heat can crack the converter or melt insulation.
