8. If out of specification, check wire harnesses for open and
short. If wire harnesses are in good condition, replace MAP
sensor and recheck.
TPS (Throttle position sensor)
! 09930-99320: Digital tester
09930-89340: 26-pin & 34-pin test cord
$ Tester range: %(DCV (See chart for range.)
1. Turn ignition switch OFF.
2. Connect the 24-pin & 34-pin test cord between ECM and
wire harness as shown in figure.
3. Connect tester probe ("+", Red) to No.16 terminal.
4. Connect tester probe ("-", Black) to No.49 terminal (or to
body ground).
5. Turn the ignition switch ON.
6. Check for sensor output voltage.
Slowly move the throttle lever to open, and check if voltage
changes linearly within specification, according to throttle
valve opening angle.
Sensor output voltage:
FCT position : Approx. 0.7 V
WOT position : Approx. 3.8 V
NOTE:
Do not try to adjust or remove any of the throttle body compo-
nent parts (Throttle position sensor, throttle valve, throttle stop
screw, etc.).
These components have been factory adjusted to precise speci-
fications.
7. If out of specification, check wire harnesses for open and
short. If wire harnesses are in good condition, replace throt-
tle body and recheck.
