Code PO128 came up on my 2005 Explorer. Any ideas on how to correct the problem?

The device you used to read the code has the ability to reset codes. But maybe, for your safety the vehicle should be brought to a authorized dealer to make sure airbags are working correctly.

That is a Manufacturers Code

I put the code into internet explorer & got
what you see below

P1627 --PCM A/D Conversion Malfunction

PCM ---Powertrain Control Module (computer)
A/D --- I guess is a binary analog to digital function
that your not getting processed correctly

I have no idea what you do,that is why I have all the
factory manuals for my vehicles

Any other codes?

I wouldn't leap on a bad PCM,they don't fail often

A bad sensor could fool it or spike it into being confused

stop by local parts store (Autozone,Advance, etc) and have them do a free fault code test. They can print out a list of faults and clear the codes

Try this it seems to be the correct code resolution.

you are correct... there is NO dipstick

what you'll find is a double plug on the trans pan

when you remove the inner plug, with the trans fluid at 122deg you will see a slight stream of fluid

the key here is that the temp must be @122 a few degrees either way can affect the results

you need a scan tool to id the fluid temp

You may have dirty or clogged fuel injectors, may also be problems with the ignition system. Might also check the fuel pressure to make sure the fuel pump is working correctly.

Go to autozone and use their code reader. This should give you a general idea what the problem is. The code reader is attached with a cable to a diagnostic port under the edge of the dash.

For the 2008 Ford Explorer ONLY (SUV). Look under the steering wheel. There is a black fuse box near emergency brake pedal. You will need a flashlight and a dental mirror (very tight space. Look between the lower lid of the box on the slim space to the left side. Take your time, you will see a bar code and 5 above it...That's it! I found mine that way. If you are laying on your back looking up, it's the gap above your right shoulder.GOOD LUCK!

have the 02 sensors checked

Replacement engine put in with 51000 miles and now the engine light is on and the speedometer goes from 50 to 0 and then jerks
