FAULT CODE E5, N2A/N2B SENSOR EXPANDED INSTRUCTIONS
Refer to numbered steps in figure 128.
Step 4.
Check harness connector PL1 and PL3 (figure 201) atDECU, P7 at N2A sensor and P8 at N2B sensor for
tight connections.
Step 5.
Disconnect connectors PL1, PL3, P7 and P8 to check pins and sockets.
Step 7.
With PL3 disconnected, check resistance of N2A sensor at harness PL1 connector sockets BB and m
202). With PL3 disconnected, check resistance of N2B sensor at harness PL3 connector sockets B and m. In
,
each case, limit is 10.0 - 45.5Ω.
Step 8.
With P7 disconnected, check resistance of N2A sensor at sensor J7 connector pins 1 and 2. With P8
disconnected, check resistance of N2B sensor at sensor J8 connector pins 1 and 2. In each case limit is
10.0 - 45.5Ω.
Step 9.
Before tightening harness connectors PL1, PL3, P7 and P8, be sure that keyways in harness connectors are
aligned with keyways in component connectors.
Step 10.
Refer to manufacturer's procedure for checking operation of N2 pickup, wheel and drive pad.
Step 13.
Refer to manufacturer's procedure for checking operation of N2 pickup, wheel and drive pad.
Step 17.
Refer to manufacturer's procedure for diagnosing and replacing harness or N2A and N2B sensor.
Step 20.
Refer to manufacturer's procedure for diagnosing and replacing N2 components.
Step 21.
Refer to manufacturer's procedure for diagnosing and replacing harness.
Step 22.
Refer to manufacturer's procedure for diagnosing and replacing N2A or N2B sensor.
Step 25.
Refer to manufacturer's procedure for diagnosing and replacing N2 components.
