NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Enter the maintenance mode, then start the engine .

   -4. Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC
   P0201 No. 1 Cylinder Injector Circuit Malfunction
   P0202 No. 2 Cylinder Injector Circuit Malfunction
   P0203 No. 3 Cylinder Injector Circuit Malfunction
   P0204 No. 4 Cylinder Injector Circuit Malfunction

   Is DTC P0201, P0202, P0203, and/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 injector and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

2. Injector internal resistance check

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Disconnect the following connector (s).

   Injector 2P connector (problem cylinder)

   -3. At the injector side, measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Injector 2P connector (problem cylinder) : disconnected
   Test point 1	Injector 2P connector (male terminals) No. 1 (injector side) :
   Test point 2	Injector 2P connector (male terminals) No. 2 (injector side) :

   Is there 9.8 - 11 Ω at room temperature?

   YES 

   The injector is OK. Go to step 3.

   NO 

   Replace the problem injector .

3. Open wire check (IGP (INJ) //IGP (MAIN) /FI_MAIN_RLY_OUT line)

   -1. Turn the vehicle to the ON mode.

   -2. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle ON mode
   	Injector 2P connector (problem cylinder) : disconnected
   Test point 1	Injector 2P connector (female terminals) No. 1:
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   Go to step 4.

   NO 

   Repair an open in the IGP (INJ) //IGP (MAIN) /FI_MAIN_RLY_OUT wire between the injector and the relay circuit board.

4. Determine possible failure area (short in INJ line, open in INJ line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Measure the resistance between body ground and the appropriate injector 2P connector terminal No. 2 of the problem cylinder (see table).

   Test condition	Vehicle OFF (LOCK) mode
   	Injector 2P connector (problem cylinder) : disconnected

   Problem cylinder	DTC	Connector	Terminal
   No. 1	P0201	Injector 2P connector (female terminals) :	No. 1
   No. 2	P0202
   No. 3	P0203
   No. 4	P0204

   Is there 1 MΩ or more?

   YES 

   Go to step 6.

   NO 

   Go to step 5.

5. Shorted wire check (INJ lines)

   -1. Jump the SCS line with the HDS, and wait more than 1 minute.

   -2. Disconnect the following connector.

   PCM connector E (80P)

   -3. Measure the resistance between body ground and the appropriate injector 2P connector terminal No. 1 of the problem cylinder (see table).

   Test condition	Vehicle OFF (LOCK) mode
   	Injector 2P connector (problem cylinder) : disconnected
   	PCM connector E (80P) : disconnected

   Problem cylinder	DTC	Connector	Terminal
   No. 1	P0201	Injector 2P connector (female terminals) :	No. 2
   No. 2	P0202
   No. 3	P0203
   No. 4	P0204

   Is there 1 MΩ or more?

   YES 

   The INJ wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .

   NO 

   Repair a short in the INJ wire between the PCM and the injector.

6. Open wire check (INJ lines)

   -1. Jump the SCS line with the HDS, and wait more than 1 minute.

   -2. Disconnect the following connector.

   PCM connector E (80P)

   -3. Measure the resistance between appropriate injector 2P connector terminal No. 2: and the appropriate PCM connector terminal of the problem cylinder (see table).

   Test condition	Vehicle OFF (LOCK) mode
   	Injector 2P connector (problem cylinder) : disconnected
   	PCM connector E (80P) : disconnected

   Problem cylinder	DTC	Connector	Terminal
   No. 1	P0201	PCM connector E (80P)	No. 18
   No. 2	P0202		No. 21
   No. 3	P0203		No. 20
   No. 4	P0204		No. 19

   Courtesy of HONDA, U.S.A., INC.

   Is there 1.0 Ω or less?

   YES 

   The INJ wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .

   NO 

   Repair an open in the INJ wire between the PCM and the injector.
