Got an error code P04DB, IT CLEARED AFTER CHECKING FOR THE CODE

Welcome, I'm Chris (aka-Moose).

  • THE TIME I AM ONLINE, 7 days a week normally online around midday and then late evening until early morning.
  • PHONE CALLS are automatically offered by the website normally after my first reply. I complete calls where I feel it is a benefit.
  • UPLOADED LINKS I SEND, if I upload dropbox links, they will open on a home PC, often they fail on a work PC, on a phone use the box on the top right of your phone screen for direct download.

P04DB suggests the input reading of the crankcase ventilation sensor is less than 2.5 volts. Normal voltage of the sensor should indicate 3.5-4.0 volts. Access the sensor ( above and behind the alternator near the engine coolant sensor) and verify battery voltage is present to the sensor on the Violet/Green wire and that the Green/White wire is a good ground. Check the Yellow wire running between the sensor and PCM for a potential open, grounded, or shorted circuit. If the wiring checks pass then replace the sensor.

You now will see a rating scale 1=bad to-5=excellent because I have posted a full or partial answer instead of an info request. When you rate I get a portion of the deposit you made, no rating means you still paid, but I earn nothing. My goal is understanding your question, and addressing it in full detail. In return, receiving a 5-star rating. Rating does not close the post or stop the conversation. Please keep in contact and reply as much as needed. Thanks, Chris

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.

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
