Detailed Description

Standard Ignition TX118 is an engine coolant temperature sensor used to report coolant temperature to the vehicle’s engine management system. Accurate temperature input helps the control system manage fuel delivery, idle behavior, and temperature-related engine operation. This part is listed for 1983-1986 Isuzu Pickup and 1983-1984 Isuzu I-Mark applications, making it a focused replacement choice for older Isuzu cooling system service. This part cross-references CTSA152 and TS5540 for the same application.

What It Helps Address

• Incorrect coolant temperature signal to the engine control system
• Hard starting or rough running related to temperature input errors
• Temperature gauge or warning light concerns tied to sensor failure
• Cooling system drivability issues on Isuzu Pickup and Isuzu I-Mark models
• Diagnostic trouble codes associated with coolant temperature sensing

Installation Notes and Tips

Verify connector style, terminal type, and mounting style before installation. The TX118 uses a bolt-on design with a female round connector and a male bullet terminal, so matching the vehicle harness and sensor port is important for proper fitment. For best results, inspect the connector, wiring, and sealing surfaces during service on 1983-1986 Isuzu Pickup and 1983-1984 Isuzu I-Mark models.
