DTC P15A5 (85): Motor Current Sensor Circuit
Malfunction
1. Start the engine, and let it idle 10 seconds.
2. Check for Temporary DTCs or DTCs w i t h the HDS.
Is DTC P0A5E, P0A5F, P0A61, P0A62, P0A64,
P1440, P0A3F, and/or P0A65 indicated?
YES—Go to the indicated D T C s troubleshooting.
N O — G o t o step 3.
3. Reset the M C M (see page 12-6).
4. Test drive the vehicle using w i d e open throttle for
at least 2 seconds and then decelerate using light
braking.
5. Check for Temporary DTCs or DTCs w i t h the HDS.
Is DTC P15A5 indicated?
Y E S — G o t o step 6.
NO—Intermittent failure, system is OK at this t i m e .
Check for poor connections or loose terminals at
the motor power cable, U/V/W phase motor current
sensor, and the M C M . •
6. Check the U PHASE MOTOR CURRENT SENSOR,
V PHASE MOTOR CURRENT SENSOR, and
W PHASE MOTOR CURRENT SENSOR in the DATA
LIST w i t h the HDS individually w i t h idle.
Does the data stick OA?
YES—Replace the the U/V/W phase m o t o r current
sensor that caused the data to stick, then go to

the motor stator (see page 12-148).
12. Measure resistance between the m o t o r power
cable terminals (A) and (B), (B) and (C), (C) and (A)
individually.
NOTE: Use 250 V range of the insulation resistance
tester.
Is there 350 kQ or higher?
YES—Replace the MPI m o d u l e (see page 12-144),
then go to step 13.
NO—Replace the m o t o r power cable (see page
12-148), then go to step 22.
