6E1-134 DRIVEABILITY AND EMISSIONS
Diagnostic Aids
Check for the following conditions:
• Poor connection at ECM - Inspect harness
connectors for backed-out terminals, improper
mating, broken locks, improperly formed or
damaged terminals, and poor terminal-to-wire
connection.
• Damaged harness - Inspect the wiring harness for
damage. If the harness appears to be OK, observe
the throttle position display on the Scan Tool while
moving connectors and wiring harnesses related to
the throttle Position sensor. A change in the display
will indicate the location of the fault.
