Ok guys, 94 f150 5.0 4X4 a4od. I posted awhile back about hard shifts and jumping speedo, you guys recommended I pull codes. So I just did it with the CeL and this is what I got 123 145 262 845 I went through it a few times and that's what I came up with. Defiantly can be confusing. So any help with those codes would be great, truck is really starting to act up. Thanks guys.

 

Here's a rundown..
123: Throttle posistion sensor above maxium voltage
145: ?
262: ?
845: ?

I can't help you on the "?"'s for codes not listed. They aren't listed in my Ford Code Reader book. You may need to re-run the Self-Test again, and be sure you are getting the correct codes listed as "?"'s

Hope this helps.

EDIT:If code 145 is actually 144, it means "HEGO sensor switch fault".

 

always start with the first code if you pull your tps autozone use to check them if not you can check it on the car i cant remember the pins but ill look for my notes in the garage

 

Thanks guys, I was digging around online and couldn't find those other codes either. I thought I was reading it right went through it a bunch of times. It was the first time I ever did it. I'll digest what I learned so far and try again in the morning.

 

for your throttle position sensor you can test it very easily, all you need is a multimeter. I just went through this, not like you, nothing transmission related, but I had to test the PTS as well as other sensors. I found a video on youtube that goes through the process.
good luck and it would definetly help if you verify the other codes. Oh and i don't think it matters but my truck is a 96 with obdII

I would try to get the codes again before spending too much time diagnosing a potential problem. If there aren't definitions for the codes, they aren't valid codes. There is a diagram here that may help decipher the blinks and pauses (the example is 2-digit, but add another 2 second pause and flash before the 4 second pause): EEC IV Self Test hookup

 

Or buy an Equus 3145 code reader for around $30.00. Takes the pain away.

 

Listen to the wise man. ^

 

I went and tried to buy one yesterday but none of the stores around here had one, all the ones they had were for obdll. It's frustrating me cause I usually don't have any problem figuring stuff like that out. I haven't tried yet today I will once I have a shady spot to work in later.

Just order an equus 3145 from amazon, be here on wednesday. Thanks for all the input so far guys.
