MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
3. Inspect water-in-fuel wiring
1. If damaged, replace water-in-
harness connector W24 C1 for
fuel wiring harness (WP 0334,
damage (WP 0451, Vol 3,
Vol 2 and WP 0336, Vol 2).
Figure 45).
2. If no damage is found, restore
equipment to original condition,
and proceed to next
malfunction.
2. Sensor resistance error.
1. Disconnect water-in-fuel wiring
harness connector W24 C2
from engine ECM wiring
harness connector W25 C8
(WP 0451, Vol 3, Figure 45).
2. Inspect water-in-fuel wiring
1. If damaged, replace water-in-
harness connector W24 C2 and
fuel wiring harness (WP 0334,
connector pins for damage.
Vol 2 and WP 0336, Vol 2).
2. If no damage is found, restore
equipment to original condition,
and proceed to next
malfunction.
3. Measure resistance between
water-in-fuel harness W24 C2
water-in-fuel sensor SIGNAL
pin (pin 1) and RETURN pin
(pin 2) (WP 446, Vol 3). Record
measurement.
4. Disconnect water-in-fuel sensor
harness W24 C1 from water-in-
fuel sensor (WP 0451, Vol 3,
Figure 44).
5. Measure resistance between

test.
pin (pin 1) and RETURN pin
(pin 2) (WP 0443, Vol 3).
2. If resistance is less than 100
kΩ, replace water-in-fuel wiring
harness (WP 0334, Vol 2 and
WP 0336, Vol 2).
