Engine Controls - Sensor Operating Range Charts Mitsubishi Mirage V

INTRODUCTION

Sensor operating range information can help determine if a sensor is out of calibration. An out-of-calibration sensor may not set a diagnostic trouble code, but it may cause driveability problems. For sensors not listed in this article, see appropriate SELF-DIAGNOSTICS article.

Note. Unless stated otherwise in test procedure, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. For connector terminal identification, see TERMINAL IDENTIFICATION in SELF-DIAGNOSTICS - INTRODUCTION article.

Note. On Diamante equipped with Traction Control (TCL) an accelerator pedal position sensor is used in place of a throttle position sensor.

Note. Measure throttle position sensor total and variable resistance between specified TP sensor terminals. (Scheme 5)and (Scheme 6). See TP SENSOR TEST TERMINAL IDENTIFICATION table. Total resistance should be 3500-6500 ohms. Variable resistance should change smoothly between 3500 and 6500 ohms as throttle valve is moved from closed to wide open throttle.
