99 Ranger with problems

[fote03]

My truck stopped running the other day. I found the radiator was leaking and the O2 sensors were bad. Well I replaced the all three o2 sensors and finally got it started after 20mins of pumping the gas and trying to start it. Tons of white smoke came out of my exhaust and and truck stalled. Couple more minutes and got it started and drove down the road abt 1/8 mile turn around and it stalls another couple of try's to get it started drove home. Plugged in Innova 3030 gives me PO340 & P1400.

I came up with
PO340 means camshaft position sensor circuit malfunction
P1400 means DPF EGR Sensor circuit low voltage detected
White smoke...water in the engine...blow head gasket??? It has been raining like crazy an the truck has been sitting a month could the white smoke just be condensation? Is there any way to test for a blown head gasket?

Any help? Any ways to test the codes?

The test for the CMP is quite simple, and is outlined in the Haynes manual. I believe the CMP sensor is located on the left valve cover, just aft of the oil filler cap. Just unplug it, pull it, connect your probes, then wave a piece of steel in front of it.
