What It Helps Address

• Erratic throttle signal output
• Throttle response concerns tied to sensor wear
• Check engine light conditions related to throttle position feedback
• Idle quality issues caused by incorrect throttle angle reporting
• Driveability problems on traction-control-equipped Mitsubishi Diamante models

Installation Notes and Tips

Verify connector style, terminal count, and vehicle fitment before installation. TH406 uses a female connector, one plug-in connection, and three male blade terminals, so the harness and sensor interface should match the original configuration. Confirm the vehicle is one of the listed Mitsubishi Diamante or Montero Sport applications, and note that the Diamante fitment is specified for vehicles equipped with traction control.
