CODE NO.11 (P0105) MAP SENSOR CIRCUIT
(SIGNAL VOLTAGE LOW, HIGH OR PERFORMANCE PROBLEM)
NOTE:
When Code No.11 (P0105), 13 (P0120), 18 (P0110) and
19 (P0115) are indicated together, it is possible that “B/
Or” wire is open or “E02-9” terminal connections are
poor.
1. ECM (PCM)
2. ECM (PCM) connector
3. MAP sensor
4. MAP sensor connector
5. To TP sensor
6. To other sensors
STEP
ACTION
YES
NO
1
1) Disconnect MAP sensor connector with
ignition switch OFF.
2) Check voltage between “a” wire terminal of
MAP sensor connector and ground with
ignition switch ON.
Is voltage about 4 – 5 V?
Go to Step 2.
“Gr/R” wire open or short.
Poor “E02-1” connection.
If wire and connection are OK,
substitute a known-good ECM
(PCM) and recheck.
2
1) Check voltage between “b” wire terminal of
MAP sensor connector and ground with
ignition switch ON.
Is voltage about 4 – 5 V?
Go to Step 3.
“Lg/R” wire open or short.
Poor “E02-5” connection.
If wire and connection are OK,
substitute a known-good ECM
(PCM) and recheck.
3
1) Connect “b” and “c” wire terminals of MAP
sensor connector using service wire.
2) Check voltage between “c” wire terminal of
MAP sensor connector and ground.
Is voltage about 0 V?
Go to Step 4.
“B/Or” wire open.
Poor “E02-9” connection.
If wire and connection are OK,
substitute a known-good ECM
(PCM) and recheck.
4
1) Remove MAP sensor.
2) Visually inspect air pressure inlet passage
of MAP sensor for clogging.
Is there any blockage?
Clean air passage or
replace as necessary.
Go to Step 5.
5
1) Perform MAP SENSOR INSPECTION in
this section.
Is MAP sensor in good condition?
Poor connection of
MAP sensor coupler
terminals.
If connection is OK,
substitute a known-
good ECM (PCM) and
recheck.
Faulty MAP sensor.
