Start the van, within 15 mins all gauges stop functioning, then engine light comes on. Battery gauge to maximum charge, oil gauge extremely high, temp gauge no reading. If I stop, turn engine of, then restart, the gauges return to normal and function properly. But the condition returns soon after. The PCM was replaced due to a constant engine light being on. Is it possible the computer has not reset yet? Or is it just some short in the gauges.
