“C22” (P1450-H/L) AP SENSOR CIRCUIT MALFUNCTION
INSPECTION
Step 1 (When indicating C22:)
1) Turn the ignition switch to OFF.
2) Lift and support the fuel tank. (
5-3)
3) Check the AP sensor coupler for loose or poor contacts.
If OK, then measure the AP sensor input voltage.
DETECTED CONDITION
POSSIBLE CAUSE
C22
AP sensor voltage is not within the fol-
lowing range.
0.5 V
Sensor voltage < 4.85 V
NOTE:
Note that atmospheric pressure varies
depending on weather conditions as
well as altitude.
Take that into consideration when
inspecting voltage.
• Clogged air passage with dust
• AP sensor circuit open or shorted to ground
• AP sensor malfunction
• ECM malfunction
