6E2-36 ENGINE AND EMISSION CONTROL SYSTEM (H25 ENGINE)
6) Turn ignition switch ON and check voltage between C51-3-
23 and C51-3-21 terminal.
MAF sensor output signal standard voltage
0.5 – 1.0 V
7) Start engine and check that voltage is lower than 5 V and it
rises as engine speed increases.
(Reference data : 1.5 – 1.8 V at specified idle speed)
If check result is not as specified above, cause may lie in
wire harness, coupler connection, MAF sensor or ECM
(PCM).
REMOVAL
1) Disconnect negative cable at battery and coupler from MAF
sensor (2).
2) Remove throttle body (1), referring to “Throttle Body” in this
section.
INSTALLATION
1) Install throttle body, referring to “Throttle Body” in this section
2) Connect coupler to MAF sensor and negative cable to bat-
tery.
Intake air temperature (IAT) sensor
REMOVAL
1) Disconnect negative cable from battery.
2) Disconnect IAT sensor coupler.
3) Remove IAT sensor from air cleaner case.
[A] : Terminal arrangement of ECM (PCM) coupler viewed from harness side.
NOTE:
Don’t remove MAF sensor.
CAUTION:
• Do not expose MAF sensor (throttle body) to any
shock.
• Do not blow compressed air by using air gun or the
like.
• Do not put finger or any other object into MAF sensor
and keep away from net. Malfunction may occur.
