96 Dodge ram B2500, 5.2 120k original miles.
Q: 3 days ago, after running well, Idle dropped, van stalled. Drove it home and next day checked codes.
505:Idle air control-short or open.
123:TPS sensor-voltage high
118:ECT voltage high
113:Intake air sensor:voltage high
1492:amb batt. Temp-too high.
Upstream 02 code was also there, so I replaced that. After replacement, no start, only cranking. Also replaced idle air control and TPS sensors, same condition. Found upstream 02 wires on female plug were all exposed. I isolated and insulated them today, no change. What next? No spark, no fuel it seems.
have the same problem?
