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

Exhaust High Temperature Sensor ?

This exhaust temperature sensor is a key safety and performance part in the hot side of the exhaust system. It is needed to measure extreme heat near the turbine, manifold, or catalyst area, so the ECU can protect the engine and exhaust components under heavy load. When temperatures rise too fast, the system can adjust fueling, boost strategy, and regeneration control (where used) to keep parts from overheating.

How It Works ⚙️

The sensor sits in the exhaust stream and reads heat levels in real time. It converts temperature into an electrical signal the ECU understands. With correct readings, the vehicle maintains stable power, safer exhaust temperatures, and better catalyst protection during towing, long climbs, or hard acceleration.

What Happens If It Fails ❌

A faulty sensor may send false high/low readings or drop out completely. This can trigger warning lights, limp mode, poor throttle response, higher fuel use, and overheating risk for the turbo/catalyst. In worst cases, excessive exhaust heat can shorten the life of nearby components.

Common Signs

• Check Engine light
• Loss of power under load
• Erratic boost or heat-related limp mode

Compatibility ✅

• Challenger
