Dunn. Cose P1633 on a 2004 Ford F-150 2wd 1/2ton

Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

Started truck and seemed to take longer then usual to "fire". Finally started and once the idle went to normal it then dropped to around 600rpm and the check engine light came on. Drove it and everything seemed to run fine. When i went to start it again a little later it had a rough start again and then i went to AutoZone. They said it was showing as a voltage surge and battery was bed. Bought new battery and replaced and code still came on. Checked alternator and starter all were fine. Code P1633 is the current code that is showing. On a side note 3 days ago i cleaned my engine compartment. could i have gotten something wet or shorted out? if so where should i begin looking?

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.

9 dollars, 2 hours of my time, and I drove away. Your diagnosis was right on the mark. Thank you so much.
