Troubleshooting
Caution
when using the multi-circuit tester, do not strongly touch the terminal
of the ecm coupler with a
needle pointed tester probe to prevent terminal damage. |
Note
after repairing the trouble, clear the dtc using sds tool. Refer to “use

- Turn the ignition switch off.
- Lift and support the fuel tank. Refer to “fuel tank removal and
installation” in section 1g .
- Remove the air cleaner box. Refer to “air cleaner box removal
and installation” in section 1d .
- Check the cmp sensor coupler (1) for loose or poor
contacts.
If ok, remove the cmp sensor. Refer to “cmp sensor removal and
installation” in section 1c .
- Connect 3 new 1.5 V batteries in series, 1 kΩ
resistor
and the multi-circuit tester as shown in the figure.

voltage ( )
- Under this condition, if a suitable screwdriver touching
the pick-up surface of the cmp sensor is moved, the
tester reading voltage changes (0.8 V and less . 4.3 V
and more).
Is the voltage ok? |
- B/y, r or b/br wire
open or shorted to
ground.
- Loose or poor
contacts on the cmp
sensor coupler or
ecm coupler
(terminal “7”, “8” or
“35”).
- If wires and
connection are ok,
intermittent trouble or
faulty ecm.
- Recheck each
terminal and wire
harness for open
circuit and poor
connection.
- Replace the ecm
with a known good
one, and inspect it
again.
