NOTE: Preliminary checks may be performed on
this component using the diagnostic mode on the
LCD gauge (see EFI Diagnostic System in this sec-
tion)
TESTING
1. Remove the left-side engine cover; then disconnect
the three-wire TPS connector plug.
NOTE: Prior to testing the TPS, inspect the three-
wire plug connector on the main harness and the
three-pin plug on the TPS for contamination, bro-
ken pins, and/or corrosion.
NOTE: If the vehicle is in warranty, removing or
adjusting the TPS will void warranty. If the TPS is
tested out of specification, the throttle body must
be replaced. If the vehicle is out of warranty, the
TPS may be adjusted.
2. Connect the TPS Multi-Analyzer Harness connector
#8 to the TPS; then connect the harness to the TPS
Analyzer Tool.
