16. Disconnect the 3P connector from each of these
sensors, one at a time, and check for continuity
between body ground and PCM connector terminal
C19 and C28 individually.
• Manifold Absolute Pressure (MAP) sensor
• Exhaust Gas Recirculation (EGR) valve position
sensor
• Throttle Position (TP) sensor
• Fuel Tank Pressure (FTP) sensor
Repair short to body ground in the wire
between PCM (C19) and the MAP sensor, or PCM
(C28) and the TP sensor, EGR valve position sensor
or FTP sensor.
Replace the sensor that made continuity to
body ground go away when disconnected.
17. Disconnect the injectors and IAC valve connectors.
18. Turn the ignition switch ON (II).
19. Measure voltage between body ground and PCM
connector terminals B1 and B9 individually.
Go to step 20.
Check for these problems:
• An open in the wire(s) between the PGM-FI main
relay and PCM connector terminals B1 and B9.
• Poor connections at the PGM-FI main relay.
• A faulty PGM-FI main relay (see page 11-209).
20. Reconnect the connectors to the sensors, then
reconnect PCM connector C (31P).
21. Turn the ignition switch ON (II), and measure
voltage between body ground and PCM connector
terminals B2, B10, B20, and B22 individually.
Substitute a known-good PCM and recheck
(see page 11-5). If the symptom/indication goes
away, replace the original PCM.
Repair the open in the wire(s) between G101
and the PCM (B2, B10, B20, B22) that had more
than 1.0 V.
22. Turn the ignition switch OFF, then turn it back ON
(II), and measure voltage between PCM connector
terminal A10 and body ground.
Go to step 26.
Go to step 23.

Is ther e continuity?
Is ther e batter y voltage?
Is ther e less than 1.0 V ?
Is ther e about 5 V ( or batter y voltage)?
