IV changed my crank sensor, tp sensor, new plugs wire,cap,etc. But I always had, a stalling issue and a code p0132, that I couldn't get rid of..finally I replaced my computer, which helped alot...still had some intermittent stalling at some red lights ..long story short, the weather got a bit colder, and truck ran like a champ.(no more stalls, truck idles constant 600 rpm,beautiful!!very happy)until I ran the diagnostic,which gave me some codes p1281,p0132,p0135, and p0138...i changed the thermostat, and both 02 sensors. I thought after all this..it just might shut off my "engine light"..NOPE, I did lose all codes but p0132..the thing is my truck is starting the bull**** with the idle jumping around,back to some stalling, idleing at 900-1000 rpms while I'm in traffic...or under 600 rpms in traffic, which in turn makes my truck like to bounce as if it wants to take off(launch)....again I hope this is not serious, but is there any other avenues I should be looking at. To get her back to a steady purrr..HELP ME anyone!!!z thanks guys

 

Did you reset the PCM after all new parts?

 

P0132 1/1 O2S Shorted To Voltage

Check the O2 sensor on the drivers side before the CAT. Also check the harness for fluids, contamination, or corrosion.

P0135 1/1 O2S Heater Failure
P0138 1/2 O2S Shorted To Voltage
P1281 Engine is Cold Too Long

These could have been triggered because your T-stat is bad and your engine is running cold. Replace the T-stat and replace the engine coolant temp sensor.

 

5.9 litre, I thought there were only 2 oxygen sensors..right? Then I did change them both..now someone had said something about power steering fluid getting in the wire harness, and shorting something ..the wires seem ok, they are wrapped in some kind of plastic..not sure..also does anyone know why I can stop my engine fan with my finger?? I dont think I should be able to do this right?...and my little plastic fan ...is this just for show??n because it never seems to work... I hate to ask soo many questions guys, but it seems that everyone (local mechanics)just want money and are reluctant to give away information, they actually seem threatened when I ask for any typ e of help..like I'm taking money from THEM!!! I dont get it..anyway any suggestions with my fan that won't spin.?? Thank you all!

 

Well I don't think that the mechanical fan should be stopped by your finger. But it won't be engaged when the engine is that cold. The electric fan should be on with the a/c or when the engine temp gets to high, so switch on the a/c and check then.

 

you should NOT be touching the clutch fan when the engine is running, simply test it by spinning it by hand while the engine is off, if it spins more than 1/2 a turn after you let go of it its shot and the clutch needs to be replaced.


also the electric fan should go on whenever the A/C is on, if its not going on at that point you should check the relay (in the PDC, simply swap it with one of the same number) and if that doesnt fix it try to jump 12v directly to the fan plug near the bottom of the radiator to see if the fan motor is bad.

 

What year are we talking about?

You come out asking questions without giving information we need. Please give year, engine, trans and drive train.

5.9L has at least 3 - O2 sensors.
