95 dodge ram 1500 4x4 5.9....codes 11-12-21-31-32-37-46...runs good, long shift out of first gear. Stalls if left to idle to long in and out of gear. No smoke or apparent misfire.

 

11 No crank reference signal at PCM. That one right there will cause a fair few problems.
12 is nothing to concern yourself about.
21 O2 stays at center, or, shorted out. Still the original sensor?
31 and 32 are emissions control codes. (EVAP, and EGR, respectively.) control circuit malfunction.
37 TTC control circuit.... the PCM tells it to engage, but, doesn't see the RPM drop it wants.
46 Charging system, voltage too high.......

 

Tested charging system at autozone, altenator tested good, battary weak. I just bought the truck. O2 sensor could be original. A couple of vacum leaks I'm working on but I'm no electriction. New cap rotor and wires. Plugs due to be shipped in a day or so.

 

Tested charging system at autozone, altenator tested good, battary weak. I just bought the truck. O2 sensor could be original. A couple of vacum leaks I'm working on but I'm no electriction. New cap rotor and wires. Plugs due to be shipped in a day or so. Code 11, it runs, is this a wire short, disconnect or broken?

 

Start with basic maintenance. (which you already have a good start on. ) Clean the throttle body, while it's off, take a look at the plenum. (inside the intake manifold) see any oil pooling in there?

Weak battery *might* be a contributor to some of your electrical issues. These trucks are really sensitive to that kind of thing.

New O2 sensor may not be a bad idea either, considering the code..... NTK or Denso sensor only please, don't bother with bosch. Our trucks don't like 'em.

 

Ok. I'll start on the batt, 02 and I will check/clean intake, good to do before new plugs anyway. Then I'll hit the zone again for a vac diagram. My phone and printer interface doesn't agree with autozones website. Update to follow. Thanks.

 

You can download the factory service manual from the faq section here. That will be a great help as well. Check the service manual thread.

 

So 02 not even plugged in, plug ends dont match, someone stopped there. I ordered the right one from Amazon so it's going to be a few days before I get it. Egr valve gunked up bad, ordered it too. Still need help on code 11. Code 31 evap short, could not find evap canister where is it? Code 46, I have a battary from another vehicle my x girlfriend totaled. Its charging, if you followed the thread batt tested bad and alt good. That's a tomorrow trial. Plugs near trans for code 37...picture show a plug I could not find the other end to. Any help there?

 

Get the service manual. It will tell you what all the connectors are, and where they should go.

 

Could not find it. Do you have URL?
