Detailed Product Overview

TX351 monitors EGR valve temperature as part of the emissions control system, helping the engine control module track exhaust gas recirculation operation. Standard Ignition TX351 is specified with a plug-in connector type, one connector, and a female rectangular housing, making it a practical replacement when the original sensor connection is damaged or the sensor has failed. This part cross-references CTSB10007 and TS7336 for the same application.

Common Issues This Sensor Can Address

  • Check engine light related to EGR temperature sensor faults
  • Incorrect EGR temperature readings reported to the engine control system
  • Emissions system diagnostic trouble codes tied to EGR monitoring
  • Rough running or drivability concerns caused by faulty EGR feedback
  • Failed sensor connection at the plug-in terminal interface

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle application before installation. TX351 uses a plug-in attachment method with two male blade terminals, so the harness connector should match the rectangular female sensor interface. Confirm the original sensor location and inspect the connector for corrosion, heat damage, or bent terminals before installing the replacement.
