Standard Ignition TS-235 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender Overview

Standard Ignition TS-235 is an engine coolant temperature sender built for accurate thermal switching in cooling system control circuits. It uses a bolt-on design with a female round plug-in connector and M14 x 1.25 threads for a secure electrical and mechanical connection.

Fits 2006-2011 Honda Civic, front right. Fits 2006-2011 Honda Civic, front left. Fits 2006-2011 Honda Civic, rear. Fits 2006-2011 Honda Civic, center. Fits 2006-2011 Honda Civic, engine bay applications where an M14 x 1.25 sender is specified.

Key Features

• Standard Ignition TS-235 engine coolant temperature sender
• Bolt-on attachment method for straightforward mounting
• Female round connector with plug-in terminal interface
• Single male blade terminal for electrical connection
• M14 x 1.25 thread size for specified applications
• Factory-calibrated and tested for switch actuation at the target temperature
• Uses a formed bimetal contact arm for precise thermal response

Detailed Description

TS-235 is engineered for cooling system temperature signaling where a calibrated sender is required to trigger or inform fan control logic. Standard Ignition uses controlled thermal materials and calibrated switch points so the unit responds at the specified lower-temperature set point. The formed bimetal contact design relies on different expansion rates between two fused metals to create consistent contact movement and electrical signal transfer.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. For buyers searching by vehicle, TS-235 is a practical match for Honda Civic coolant temperature sender replacement needs when the original unit uses the same connector and thread specification.

Common Problems This Part Can Address

• Cooling fan not switching on at the correct temperature
• Erratic temperature signal to the fan controller
• Hard starting or drivability issues tied to incorrect coolant temperature input
• Warning light or gauge behavior caused by a failing sender
• Intermittent electrical contact at the coolant temperature switch

Installation Notes and Tips

Confirm the connector style, terminal layout, and M14 x 1.25 thread size before installation. Clean the mounting area and inspect the harness plug for corrosion or looseness before connecting the sender. Because this is a temperature-sensitive electrical component, verify the cooling system is in proper condition and follow the vehicle service procedure for coolant level and thread sealing requirements.

Quality Assurance

Standard Ignition states that each thermal switch is calibrated and tested during production to confirm actuation at the specified temperature. The brand also maintains quality control from component selection through finished product assembly, supporting consistent performance for service replacement use.
