Is DTC P0201, P0202, P0203, or P0204 indicated?
YES : The failure is duplicated. Go to step 2.
NO : Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at
the injectors and the PCM.
2. Injector internal resistance check:
ο‘
1. Turn the ignition switch to LOCK (0).
2. Disconnect the following connector(s).
ο‘
Injector 2P connector (problem cylinder)
ο‘
3. At the injector side, measure the resistance between test points 1 and 2.
Test condition IG LOCK (0)
Injector 2P connector (problem cylinder): disconnected
Test circuit IGP(INJ), INJ
Test point 1 Injector 2P connector No. 1 (injector side)
Test point 2 Injector 2P connector No. 2 (injector side)

Is there 10-13 ohms?
YES : The injector is OK. Go to step 3.
NO : REPLACE THE PROBLEM INJECTOR , then do the repair verification .
3. Open wire check (IGP line):
ο‘
ο‘
1. Turn the ignition switch to ON (II).
2. Measure the voltage between test points 1 and 2.
Test condition IG ON (II)
Injector 2P connector (problem cylinder): disconnected
Test circuit IGP(INJ)
Test point 1 Injector 2P connector No. 1 (YEL)
Test point 2 Body ground

Is there battery voltage?
YES : The IGP(INJ) wire is OK. Go to step 4.
NO : Repair an open in the IGP(INJ) wire between the injector and PGM-FI main relay 1, then do the
repair verification .
4. Determine possible failure area (INJ line short, INJ line open):
ο‘
1. Turn the ignition switch to LOCK (0).
ο‘
2. Check for continuity between body ground and the appropriate injector connector terminal of the
problem cylinder (see table).
Test condition IG LOCK (0)

5. Shorted wire check (INJ lines):
ο‘
1. Jump the SCS line with the HDS.
ο‘
2. Disconnect the following connector.
PCM connector C (49P)
ο‘
3. Check for continuity between body ground and the appropriate injector connector terminal of the

Is there continuity?
YES : Repair a short in the INJ wire between the PCM and the injector, then do the repair verification .
NO : The INJ wire is OK. Update the PCM See PCM UPDATE or PCM REMOVAL AND
INSTALLATION if it does not have the latest software, or substitute a known-good PCM See PCM
UPDATE or PCM REMOVAL AND INSTALLATION , then do the repair verification .
6. Open wire check (INJ lines):
ο‘
1. Jump the SCS line with the HDS.

Is DTC P0201, P0202, P0203, or P0204 indicated?
YES : Check for poor connections or loose terminals at the injector and the PCM. If the PCM was updated,
substitute a known-good PCM See PCM UPDATE or PCM REMOVAL AND INSTALLATION , then
recheck. If the PCM was substituted, go to step 1.
NO : Troubleshooting is complete. If the PCM was substituted, replace the original PCM See PCM UPDATE
or PCM REMOVAL AND INSTALLATION . If any other Pending or Confirmed DTCs are indicated, go to
the indicated DTC's troubleshooting.
