Note
-
• Perform the following inspection only when directed.
Resistance Inspection
1. Disconnect the negative battery cable.
2. Disconnect the fuel injection pump connector A.
3. Inspect the resistance between the terminals under the following condition.
-
• Consult authorized BOSCH parts distributor for repair if the CS sensor is possibly malfunctioning:
• If as specified, carry out the “Circuit Open/Short Inspection”.

Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [WL-3].)
2. Inspect for an open or short circuit in the following wiring harnesses.
-
• if there is an open or short circuit, repair or replace wiring harnesses.
Open circuit
• Power circuit (fuel injection pump connector A terminal G and PCM connector terminal 1O)
• Signal circuit (fuel injection pump connector A terminal F and PCM connector terminal 1Q)
• Ground circuit (fuel injection pump connector A terminal H and PCM connector terminal 1M)
Short circuit
• Fuel injection pump connector A terminal G and PCM connector terminal 1O short to ground
• Fuel injection pump connector A terminal F and PCM connector terminal 1Q short to ground
• Fuel injection pump connector A terminal F and PCM connector terminal 1Q short to power supply
• Fuel injection pump connector A terminal H and PCM connector terminal 1M short to power supply
