INJECTION - AIR INTAKE SYSTEM
“C22” AP SENSOR CIRCUIT MALFUNCTION
PROBLEM
POSSIBLE CAUSE
Low pressure and high voltage.
High pressure and high voltage.
(0,25V
≤
Voltage sensor
<
4,85V)
outside the indicated range.
NOTE:
Note that the atmospheric pressure varies accord-
ing to the weather conditions and the altitude.
Take into consideration these factors when check-
ing the voltage.
• Passage of air blocked by dust.
• Red/orange lead circuit open or in short-circuit to Earth.
• Black/brown lead circuit or green lead circuit in short-
circuit to Earth.
• AP sensor malfunction.
• ECM malfunction.
…
CHECK
• Remove the seat.
1
Turn the ignition switch to the OFF position.
Check to see if the contacts of the AP sensor connectors are
loose or ruined.
If OK, measure the incoming voltage of the AP sensor.
Turn the ignition switch to the ON position.
Disconnect the AP sensor connectors.
Measure the voltage between the terminal of the red/orange
lead and Earth.
If OK, measure the voltage between the terminal of the red/
orange lead and the terminal of the black/brown lead.
AP sensor incoming voltage: 4.5-5.5V
(+red/orange –Earth)
(+red/orange –black/brown)
Tester dial indication: Voltage ( — )
NO
ECM coupling contacts loose or
ruined.
Red or black/brown lead circuits
YES
open or in short-circuit.
2
Connect the AP sensor coupling.
Turn the ignition switch to the ON position. Measure the
outgoing voltage of the AP sensor at the wiring connector
between the violet/yellow lead and the black/brown lead.
AP sensor outgoing voltage: approx. 3.6V
at 760 mmHg
(100kPa)
(+violet/yellow-black/brown)
Tester dial indication: Voltage ( — )
NO
Check to see if the air passage is
blocked.
Violet/yellow lead circuit open or in
short-circuit.
Substitute the AP sensor.
YES
