A/F Sensor Inspection
1. Connect the M-MDS to the DLC?2.
2. Switch the ignition ON (engine on).
3. Warm up the engine to normal operating temperature.
4. Access the following PIDs using the M-MDS..
VSS (Vehicle speed)
RPM (Engine speed)
O2S11 (A/F sensor output current)
5. Drive the vehicle and decelerate the engine speed by releasing the accelerator pedal fully when the engine speed is 3,000 rpm or more
.
6. Verify that the A/F sensor output current (PID: O2S11) is 0.25 mA or more
while decelerating as shown in the figure.
If not as specified, replace the A/F sensor..
A/F Sensor Heater Inspection
WARNING:
A hot engine and exhaust system can cause severe burns. Turn off the engine and wait until they are cool before removing the exhaust system.
1. Disconnect the negative battery cable..
2. Disconnect the A/F sensor connector.
3. Measure the resistance between A/F sensor terminals A and E.
If not as specified, replace the A/F sensor..
1—10 ohms [normal temperature]

Camshaft Position (CMP) Sensor Inspection
Intake CMP Sensor
Visual inspection
CAUTION:
When replacing the CMP sensor, make sure there is no foreign material on
it such as metal shavings. If it is installed with foreign material, the sensor
output signal will malfunction resulting from fluctuation in magnetic flux and
caus ...
