Welcome to K-Series TPS calibration made easy. Calibrating a TPS can be difficult when there are no exposed points to contact with a multimeter. The 1875 Calibration Jumper Harness for Honda K-Series drive-by-cable throttle bodies goes between the TPS and engine wiring harness to provide convenient points to contact the Signal and Ground wires. Simply plug it in during calibration, calibrate your TPS, and remove the calibration harness upon finishing the calibration process. See our 1878 or 1879 TPS install guide for more information about TPS calibration.
