INTRODUCTION
NOTE: Unless stated otherwise in testing procedures, perform all
voltage tests using a Digital Volt-Ohmmeter (DVOM) with a
minimum 10-megohm input impedance. Voltage readings may vary
slightly due to battery condition or charging rate.
Pin voltage charts are supplied to reduce diagnostic time.
Checking pin voltages at the PCM connector determines whether it is
receiving and transmitting proper voltage signals. Diagnostic charts
may also help determine if PCM harness is shorted or open.
TEST PROCEDURE
CAUTION: Shorting positive DVOM lead between connector terminal and
ground could damage vehicle wiring, sensor and PCM.
1) If necessary, remove Powertrain Control Module (PCM) to
access harness connector. For PCM location, see PCM LOCATION table.
Leave PCM connectors connected.
2) Using DVOM, backprobe terminals. Connect positive DVOM
lead to appropriate PCM terminal. Connect negative DVOM lead to PCM
ground terminal. For PCM terminal identification, see appropriate
chart. See Figs. 1-24.
3) All measurements are applicable to vehicle at normal
operating temperature at sea level. Unless otherwise noted, engine is
idling when specification requires engine running. Ensure transmission
shift selector is in Neutral or Park (as applicable). If DVOM displays\
measurement that is not within specification, see G - TESTS W/CODES
article.

WHEEL & TIRE SPECIFICATIONS
Tire specifications are imprinted on the tire side wall. The
recommended cold tire inflation pressures are listed on a label
attached to the rear face of the driver's door. These pressures
provide the best combination of ride comfort, tire wear and stability
under normal conditions.
CAUTION: DO NOT mix tires of different design such as radial ply
with bias or bias-belted tires. Mixing tire types will
adversely affect road handling and may lead to loss of
vehicle control. When using snow tires, they must be used
in set of four for maneuverability and safety. DO NOT use
