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 G - TESTS W/CODES 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
G - TESTS W/CODES article.

( 1) - IAT sensor is incorporated in airflow sensor assembly.
Check resistance between IAT sensor terminals No. 5
and 6. See Figs. 1-4.
( 2) - Check resistance across IAT sensor terminals No. 1
and 2. See Figs. 1-4.

Throttle Position (TP) Sensor
Measure total and variable resistance between specified TP
sensor terminals. See Fig. 5 or 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.
