I told the list back in June about my bad temp 2 sensor [ only 2 years old] Thanks to DigiTool a new sensor from the dealer and a TPS alignment Got the van running like a top all summer. The cold mornings this month have brought back the grumpy / lumpy Start ups and random stalling.
This mornings grumpy / lumpy start up with high idle had Digitool Giving me the following readings for Temp II: 4.9 with high idle. [ I think 4.9 is way off the normal scale for Temp II] I remember listees mentioning the wiring for the sensor sometimes going bad - So I opened up the engine lid..
4.9v high idle 4.9v [ wiggling sensor wiring] 4.9v [ sensor disconnected!! ???] 4.9v [ sensor reconnected] I wait a minute [ van running total of 4 minutes] And then in 3 seconds the voltage reading goes..[ with the idle following it up and down] 4.9 3.2 3.8 4.9 4. 9 2.8 3.5 2.8 2. 5 2.2 1.9 1.5 1.3 [ normal for cold] And the engine runs fine at that point.
So the Temp II sensor is bad again?? This one is from the dealer and was new in June! I made a joke about carrying spares but this is crazy... And why would I still get a voltage reading With the sensor plug pulled out??
Thanks for any input.
