Test QC - Output State Check Not Functioning

NOTE: Perform this CIRCUIT TEST when directed by other test procedures. This test is intended to diagnose only the following:

ECA
Harness circuits (SIG RTN, STO, STI, GND, VPWR, & VREF)

1) Check For Codes 23,53,63 or 68 If vehicle is equipped with a speed control, speed control servo must be electrically disconnected. This prevents the speed control system from affecting throttle plate movement during Output State Check. Rerun QUICK TEST or Output State Check.

Turn key off and wait 10 seconds. Perform KOEO Self-Test. If Codes 23, 53, 63 or 68 are displayed, go to KOEO Self-Test table and service code(s) as necessary. If no codes are displayed, go to TEST QA, step 1. If Code 11 (Pass) is displayed, go to next step.

2) Check Throttle Linkage Check throttle and linkage for sticking or binding. If throttle and linkage are okay, replace TPS and repeat QUICK TEST. If throttle and linkage are binding, repair as necessary and repeat QUICK TEST.
