Mercedes Sprinter EGR Exhaust Temperature Sensor – Bosch OEM | OM642 3.0L | #0071538428 (2010–2022)

TITLE: Mercedes Sprinter EGR Exhaust Temperature Sensor – Bosch OEM | OM642 3.0L | #0071538428 (2010–2022)

DESCRIPTION:

The exhaust gas temperature sensor downstream of the EGR cooler is a critical monitoring point in the OM642's emissions system — and a failed or inaccurate sensor can trigger fault codes, disrupt EGR operation, and interfere with DPF regeneration cycles. This is the Bosch OEM EGT sensor positioned downstream of the EGR cooler on the 3.0L OM642 Sprinter, restoring accurate exhaust temperature feedback to the ECU and emissions control system.

What This Part Does

This exhaust gas temperature sensor monitors exhaust gas temperature at a specific point downstream of the EGR cooler. The ECU uses this data to manage EGR valve operation, DPF regeneration timing, and catalytic converter protection. When the sensor fails or reads out of range, the ECU loses accurate temperature data at this point in the exhaust circuit — leading to fault codes, incorrect EGR behavior, missed regeneration events, and in some cases, limp mode activation.

Common Symptoms of a Failing EGT Sensor

• Check engine light with exhaust temperature sensor fault codes
• P0544, P0545, P0546 — exhaust gas temperature circuit codes
• Irregular or absent DPF regeneration cycles
• EGR system fault codes occurring alongside temperature codes
• Reduced engine performance or limp mode

Sensor Position

This sensor is located downstream of the EGR cooler in the exhaust recirculation circuit. The OM642 Sprinter uses multiple EGT sensors at different positions — always verify the correct sensor location and part number for your specific fault before ordering.
