I2: CHECK HARNESS +VE CONTIN UITY (INPUT SPEED SENSOR)
With EM007 and EM046 disconnected, measure the resistance between EM046/005 and EM007/042 1
Is the resistance < 0.5 OHM?
Yes
Reconnect EM046
GO to I3
No Inspect harness / connectors EM007 and EM046 for damage,
corrosion, bent / pushed back pins. Repair as necessary and
test the system for normal operation.
I3: CHECK HARNESS -VE CONTINUITY (INPUT SPEED SENSOR)
Page 1323 of 2490
With EM007 and EM046 disconnected, measure the resistance between EM046/014 and EM007/006 1
Is the resistance < 0.5 OHM?
Yes GO to I4
No Inspect harness / connectors EM007 and EM046 for damage,
corrosion, bent / pushed back pins. Repair as necessary and
test the system for normal operation.
I4: CHECK INPUT SPEED SENSOR COIL CONTINUITY
Page 1324 of 2490
With, EM007 disconnected, measure the sensor value
between EM007/042 and EM007/014 1
Is the resistance between 280 and 1200 OHM?
Yes GO to I5
No Renew the input speed sensor
I5: CHECK HARNESS +VE CONTIN UITY (OUTPUT SPEED SENSOR)
Page 1325 of 2490
With EM007 and EM046 disconnected, measure the resistance between EM046/001 and EM007/016 1
Is the resistance < 0.5 OHM?
Yes Reconnect EM046
GO to I6
No Inspect harness / connectors EM007 and EM046 for damage,
corrosion, bent / pushed back pins. Repair as necessary and
test the system for normal operation.
I6: CHECK HARNESS -VE CONTINUITY (OUTPUT SPEED SENSOR)
Page 1326 of 2490

Yes GO to I7
No Inspect EM007 and EM046 for corrosion, bent / pushed back
pins or locate and repair th e harness Test the system for
normal operation
I7: CHECK OUTPUT SPEED SENSOR COIL CONTINUITY
Page 1327 of 2490
With, EM007 disconnected, measure the sensor value
between EM007/016 and EM007/044 1
Is the resistance between 280 and 1200 OHM?
Yes GO to I8
No Renew the output speed sensor
I8: CHECK FOR SHORT TO B+
Page 1328 of 2490
With EM007 disconnected, measure the voltage between
EM007/016 and EM007/026 1
Repeat for EM007/026 and EM007/044 2
0V?
Yes GO to I9
No Inspect harness / connectors EM007 and EM046 for damage,
corrosion, bent / pushed back pins. Repair as necessary and
test the system for normal operation.
