3-94 FUEL SYSTEM (DFI)
Stick Coils #1, #2, #3, #4 (Service Code 51, 52, 53, 54) (DTC P0351, P0352, P0353,
P0354)
  Inspect the eligible stick coil according to the following
service code or DTC.
   Service Code 51/DTC P0351 → Stick Coil #1
   Service Code 52/DTC P0352 → Stick Coil #2
   Service Code 53/DTC P0353 → Stick Coil #3
   Service Code 54/DTC P0354 → Stick Coil #4
Stick Coil Removal/Installation
• Refer to the Stick Coil Removal/Installation in the Electri-
  cal System chapter.
Stick Coil Primary Winding Resistance Inspection
• Refer to the Stick Coil Inspection in the Electrical System
  chapter.
    If the reading is within the standard, check the input volt-
    age (see Stick Coil Input Voltage Inspection).
Stick Coil Input Voltage Inspection
• Turn the ignition switch off.
•○Do not disconnect
   Remove  the ECU (see ECU Removal).

    Stick Coil Input Voltage
      Connections to ECU Connector:
        For Stick Coil #1
          Digital Meter (+) → BK lead (terminal 44)
          Digital Meter (–) → Frame Ground Terminal
        For Stick Coil #2
          Digital Meter (+) → BK/R lead (terminal 55)
          Digital Meter (–) → Frame Ground Terminal
        For Stick Coil #3
          Digital Meter (+) → BK/O lead (terminal 66)
          Digital Meter (–) → Frame Ground Terminal
        For Stick Coil #4
          Digital Meter (+) → BK/G lead (terminal 43)
          Digital Meter (–) → Frame Ground Terminal

• Measure    the input voltage to each primary winding of the
  stick coils with the engine stopped and with the connec-
    tors joined.
•   Turn the engine stop switch to run position.
•   Turn the ignition switch on.
    Input Voltage
      Standard: Battery Voltage

• Turn   the ignition switch off.
  If the input voltage is out of the standard, check the wiring
    for continuity (see Stick Coil Circuit).
    If there is no continuity, repair or replace the main har-
    ness.
