Codes

Akquad12 · Dec 2, 2015

Hi, just installed a ts chip, edge cts monitor, straight piped to a stack. No I'm getting a p0340, and a p0472 code. And now the tranny won't stay in top gear unless wot while on the hwy. Help please. Sorry it's a 1997 f350.

You may need a new cps.

and you need to clean the ebp tube and Sensor. Can be the cause of your issues.

Oh also the factory ford high idle box won't idle up anymore.

I'm not exactly sure, but it may not engage if there's a engine light on.
But doesn't that one plug into the obd port? If so, did you unplug it when you hooked the CTS up?

No doesn't plug into the ob2 plug. Worked until today and is not showing a check engine light just reading the codes off the cts

Then replace the cps.
I know it has to read RPM, so start there. It's cheap.

Changed the cps and has a bad miss now.
Got a grey one from napa and installed it and it wouldn't start.
Got a black one for 94 to 96 and runs but has a bad miss.

Try the one from advanced auto.
Still misses with the ts unplugged?

Haven't tried to pull the chip yet. Monitor reads no bad codes says system pass. Idles fine. But if I rev and hold it up around 1500 rpm or more has a miss and above 2000 rpm loads up and spudders till it cleans out then revs up.

Get a CPS from the dealer, the ones from part stores are questionable.

Also pull the chip unless you were having these problems before you installed it and if you did have these problems why did you install the chip?

Yeah called a local diesel shop lady told me to get a ford one so I did runs perfect. Thanks for the help everyone.

Took it to the shop for the tranny and abs light. They said 97 and assuming older fords don't like led lights. I put in led lights in my Flatbed then started having the problems. Anyone hear of this before or know how to fix it so I can run led tail lights?
