Product Details
Walker Products HD focuses on engine management and fuel system components built to meet or exceed OEM standards, backed by in-house manufacturing, engineering, and technical support. Part number 1003-1052 is an exhaust gas temperature sensor used to monitor exhaust heat levels so the vehicle’s control system can manage emission-related functions more accurately. For buyers searching for a Walker EGT sensor, exhaust gas temperature sensor replacement, or a heavy-duty emission control sensor, 1003-1052 is a direct-fit style option to verify against the original connector and thread specifications. It is also a relevant replacement search for diesel applications such as Ford Super Duty, Chevrolet Silverado HD, and Ram heavy-duty trucks when the original sensor matches these dimensions.
Common Issues This Part Can Address
- Fault codes related to exhaust gas temperature sensor performance
- Inaccurate exhaust temperature readings in the emission control system
- Connector or terminal mismatch during sensor replacement
- Sensor failure caused by heat exposure in the exhaust stream
- Drivability or regeneration concerns tied to faulty exhaust temperature input
Installation Notes
Confirm the original sensor thread diameter, connector shape, terminal style, wire count, and harness length before installation. Because this part mounts in the exhaust, inspect the surrounding area for heat damage, corrosion, or damaged wiring before connecting the new sensor. Verify vehicle-specific application details for your Ford Super Duty, Chevrolet Silverado HD, or Ram truck before ordering, since EGT sensor configurations can vary by engine and emissions package.
Quality Assurance
Walker Products has supplied automotive fuel system and engine sensor components since 1946 and manufactures under ISO 9001/IATF16949 quality systems. The 1003-1052 part number reflects Walker Products HD engineering standards for OEM-style replacement accuracy and technical support.
