for S/N 25451 and up
. pins 1 and 3 (>10 megohms)
. pin 1 and the ground (>10 megohms).
a If the resistance values are out of the specified limits:
_
- replace the N1 sensor (4000EV) (Ref. AMM TASK 77-11-10-000-002) and (Ref. AMM TASK 77-11-10-400-002).
b If the resistance values are in the specified limits:
_
- connect the HJ10 harness to the N1 sensor.
(b) Disconnect connector HJ10 from the ECU (4000KS) receptacle and visually examine the receptacles and the connectors for damaged pins or contamination (Ref. AMM TASK 73-21-50-210-002).
1 If damage is found:
_ - repair or replace as required.
2 If no damage is found:
_
- do the electrical resistance test through the J10 harness between: . pins 16 and 17 (40 to 80 ohms)
for S/N different than 25451 and up
. pins 16 and 6 (>5 kiloohms)
. pin 16 and the ground (>10 megohms)
for S/N 25451 and up
. pins 16 and 6 (>10 megohms)
. pin 16 and the ground (>10 megohms).

R B. Do the test given in Para. 3.A.
R (1) No additional maintenance action is required if the fault is not
R confirmed.
R (2) Repeat the fault isolation procedure if the fault continues.
