Catalytic Converter Temperature Sensor T4/T5 Upstream & Downstream | Mahindra

Catalytic Converter Temperature Sensor T4 / T5 – Upstream & Downstream | Mahindra

The Catalytic Converter Temperature Sensor T4/T5 is an exhaust temperature sensing component used in Mahindra diesel applications equipped with an exhaust after-treatment system. The sensor measures exhaust gas temperature and provides temperature information to the engine management system (EMS).

For Mahindra BS6 applications, T4 and T5 are different temperature-sensing positions. In the Mahindra Jeeto BS6 diagnostic documentation, T4 is identified as the temperature sensor at the upstream side of the Diesel Oxidation Catalyst (DOC), while T5 is positioned at the lower side of the oxidation catalyst and is used for monitoring DPF inlet exhaust temperature.

Key Features

• Catalytic converter / exhaust temperature sensor
• Available for T4 and T5 applications
• Upstream and downstream-position applications
• Designed for exhaust temperature monitoring
• Sends temperature information to the engine management system
• Used in exhaust after-treatment and emissions-control systems
• Suitable for applicable Mahindra diesel vehicles

T4 Temperature Sensor

The T4 sensor monitors exhaust temperature at the upstream side of the oxidation catalyst/DOC. The EMS uses this temperature information for exhaust after-treatment control and monitoring. (Scribd)

T5 Temperature Sensor

The T5 sensor monitors temperature at the relevant downstream/lower position of the oxidation catalyst and provides information used for DPF inlet exhaust-temperature monitoring and exhaust after-treatment control. (Scribd)

Applications

This product is intended for applicable Mahindra diesel vehicles using T4/T5 exhaust temperature sensors.

Because Mahindra uses different engine, exhaust after-treatment and sensor configurations across its vehicle range, exact vehicle compatibility should be verified before ordering.

Compatible Vehicles

Mahindra vehicles – applicable T4/T5 sensor applications.

Exact compatibility depends on the vehicle model, model year, engine, BS emission version, connector and original sensor configuration.

Please provide the vehicle model, engine/BS version, existing sensor photograph or OEM Part Number if you need compatibility confirmation.

Installation Notes

Installation should preferably be performed by a qualified automotive technician.

Before installation:

• Confirm whether the vehicle requires T4 or T5.
• Compare the original sensor with the replacement.
• Check connector type and wiring.
• Check the sensor mounting/thread configuration.
• Verify the OEM Part Number where available.
• Clear relevant fault codes and check live temperature data after installation.

Do not replace a T4 sensor with a T5 sensor, or vice versa, unless compatibility has been confirmed for the specific vehicle application.

Why Replace the Temperature Sensor?

A faulty exhaust temperature sensor can cause incorrect temperature information to be supplied to the engine management system. Depending on the vehicle system, this may affect exhaust after-treatment monitoring or control.

A sensor-related fault should be properly diagnosed before replacement because wiring, connectors and other exhaust-system components can also cause temperature-sensor-related fault codes.

Important Compatibility Note

T4 and T5 are position-specific sensors. The correct sensor must be selected according to the vehicle’s original configuration.

The OEM Part Number has not been provided in the supplied product information, so no part number is being claimed here.

For accurate compatibility checking, send:

Vehicle Model + Model Year + Engine/BS Version + Existing Sensor Photo + OEM Part Number (if available).
