Took connection of icp sensor and it had oil in it would that cause my sea light to come on and off

 

It's not a guarantee, but the likelihood is very high. I'd swap the ICP, if it were me. The most common symptom with a bad ICP is SES light with low power (barely able to get up to speed).

 

Sometimes the trucks throttle response is hesitant like it's gonna cut off then it goes away as I accelerate

 

Yeah... that ICP is suspect.

 

Are the aftermarket sensors good?

 

I wouldn't say no... I'd say hell no. Some of them will stall the truck if they get too close to somebody with a CB... or near a cell tower... or while driving by some kid running a RC car.

Riffraff Diesel has reasonable prices on OEM parts, that's who I deal with.

 

X2 on Riffraff great customer service and fast shipping. Diesel-o-rings is also a great place to get parts.

 

Ok I'll check them out thx

 

What code is it throwing when the SES light is illuminating?

Also, when the ICP sensor is not working it will default to a value of 750psi at idle. You can see this with a good scan tool. You could also try disconnecting the sensor while the truck is idling to see if the engine sound changes. If it does change, the sensor is at least operational.

 

Changed sensor but nothing changed still sea light comes on and off and a stumble at acceleration then it clears up as I pick up speed I've tried having it scanned at previous and no codes come up should I have it scanned at the dealer

 

Censor was purchased at ford dealer

 

I inspected my ICP sensor last year. It had a tiny bit of oil inside it. As a preventative measure, I replaced it with a new one from Napa.

About a week later, the truck was driven from Oregon to Anchorage, Alaska.

As the truck pulled into midtown Anchorage it lost power in the middle of an intersection, sputtered, and died. Restarted, ran like garbage, would barely move, kept dying.

Once I got to the truck I started diagnostics and unplugged the ICP sensor. Ran normally.

Luckily I had kept my old OEM one as a spare in my tool box. Swapped the new Napa sensor back to the factory one with a slight bit of oil.

Has ran great for the past 1.5 years.

Imagine if the Napa sensor had gone out in the middle of no where Canada, while someone not familiar with PSDs driving. Can you say **** creek?

Go factory sensor or nothing, just my advice.

As for your particular problem, have you tried the CPS sensor?

 

Oh... since you're not being frugal about this, it's time to amp up our game.


Keep your old ICP until this can be sorted out. ICPs are dropping like flies at this age, and you had oil in it. Chances are, if it hasn't failed yet - it will soon.


You need to read the trouble codes. There is a BEST map in my signature, ask the auto parts store if they have the ability to read Ford codes (many can't), or step up and get an OBDII scan gauge/tool. I opted for the latter and don't regret it in the least.

 

Ok will do I may jus bite the bullet and have it scanned at ford dealer

 

That's only true if the PCM knows the sensor is bad, like when it has an electrical fault. If the sensor is biased, it will probably still trust the reading.
