Thank you & more
I posted in the nOOb section but some of you may have missed it. This is an update after doing a little investigating.
But first, thank you for this most excellent resource. Without it I would still be wondering where to start...
I've been driving a 98.5 in stock form since dad handed it down last spring. The CEL has been on since, and he warned me that it was an intake heater code. Lucky for me the VAG tool for the VW that I have also reads and is compatible with the OBDII codes in the dodge. I checked the codes, did some homework and spent a bit of time outside today. Here's the results:
Resistence across heating element 1 = 1 Ohm
Resistence across heating element 2 = 1 Ohm (I don't actually know which is which)
Resistence of cable from relay 1 to element = 1 Ohm
Likewise on #2.
Cables from battery are .9 and .8 Ohm respectively.
This leaves either bad relays or a bad Intake Air Temperature Sensor (where is that thing anyway? I couldn't find it on the manifold).
But wait... what's this? One of the switch wires on one of the relays is disconnected! Could it be the problem all along?
It turns out the harness has come out of it's mounting point and has fallen enough so that the connector has pulled off the terminal. (Did I mention that I hate "push on" terminals?) Anyhow, it also appears that this wire in particular has been replaced at some point as it is now spliced and running zip-tied to the outside of the loom. Hmmm.
So I re-hung the harness, re-attached the wire (with a bit of di-electric grease) and cleared the codes. Now I have to wait for a cold morning to find out if the code will come back. The truck wouldn't heat the heaters today, it's too warm here this afternoon.
So again, thanks for all the past input you guys have made, as I got most of my information from searching the forums. Hopefully I'll have something useful to contribute one of these days.
