3.2TL TYPE S V6-3.2L SOHC (2002)
4. Turn the ignition switch ON (II), and measure voltage between PCM connector terminal A31 and body ground.
Is there about 5 V?
YES-Replace the fuel and temperature gauge assembly.
NO-Go to step 5.
5. Turn the ignition switch OFF, and check for continuity between PCM connector terminal A31 and gauge assembly connector terminal B3.
Is there continuity?
YES-Replace the fuel and temperature gauge assembly.
NO-Repair open in the wire between PCM connector terminal A31 and gauge connector terminal B3.
Coolant Temperature Gauge Needle Goes Past the Hot Mark:
1. Turn the ignition switch OFF, and disconnect PCM connector A (32P).
2. Turn the ignition switch ON (II), and watch the coolant temperature gauge.
Does the temperature gauge need to move at all ? (you may have to watch it for about 30 seconds).
YES-Go to step 3.
NO-Substitute a known-good PCM and recheck. If the symptom/indication goes away, replace the original PCM.
3. Turn the ignition switch OFF, then turn it ON (II) again, and watch the coolant temperature gauge.
Does the temperature gauge needle immediately go past the Hot mark?
YES-Replace the fuel and temperature gauge assembly.
NO-The temperature gauge needle went past the Hot mark after about 30 seconds or more. Go to step 4.
4. Turn the ignition switch OFF, and disconnect the gauge assembly connector B (18P).
5. Check for continuity between PCM connector terminal A31 and gauge assembly connector terminal B3.
Is there continuity?
YES-Repair short in the wire between PCM connector A31 end gauge connector terminal B3.
