OBD Code P0107

Have made all repairs, thanks to the forum. Cleared all CL codes and then P0107 M.A.P sensor, came up. Does any one have input? Thanks.

Ugh. That's the most pointless sensor on the entire car. It doesn't DO anything, but it will throw codes angrily if it's mad.

The MAP sensor is the black thing plugged into the pink plug right there.

Try pulling the connector off and cleaning the contacts with electrical cleaner, and then give it a good whack with a wrench. I don't know if this works, but I was getting codes thrown every day from mine, and it's shut up now for a good year and a half.

Sorry to reopen and old thread, but i am also getting the P0107 code, i cleaned the sensor, gave it a good whack and put it back in. The code stayed away for a couple days before returning.

I had a question about this that im hoping someone can answer.
Is there anyway to get the voltage that the sensor needs to be happy?
The code is for low voltage.

There was a trick i found years ago for my honda that i could use a certain resistor in the air flow sensor to trick the computer into thinking it was always 32 degrees outside. (suppose to give you a little more HP)

Which kinda got me thinking that if we could figure out what voltage it wants to be happy we could find the right resistor and wire it up at the pink connector and bypass the sensor altogether and the computer wont know the difference.

Anyone got any info on this? Could it be done?

Thanks for the help, im new to this forum and this is my first post, but ive been reading this forum for a couple weeks now.
Im also i new volvo owner and have never worked on a volvo before, and this forum has helped me tremendously with troubleshooting my 98 v70. Thanks again.

I haven't seen anything on the specs for that particular sensor. We've got values for just about every other one, but I don't know about that one.

I would try to get your hands on a used one; someone pulled one from a junkyard for me for free! So far, so good!

Thanks for the quick reply. Ill have to see if i can get my hands on a used one.

Also liked your write up on the PVC system repair.
Im sure i need to do that too, but it looks pretty involved.

That sensor shares reference voltage supply from ECM with A/C pressure sensor and the subframe mounted acceleration sensor. Either of these can fail and make the Vref low. The diagnostic detection of low voltage is not the same for the three sensors so the actual faulty sensor is not necessarily the one that will have the code.
Water inside any of the connectors you unplug from the three sensors is some times the clue.

I'm getting a P0107 code. When I clear the code, it seems to come back within 500 miles. I replaced the MAF sensor this year for preventative maintenance. Next suspect... MAP sensor?

I'll try to clean the connection to the MAP sensor. If that doesn't help, should I get this Bosch MAP sensor for ~$100?

This is a better pick and pull item for $10,especially if the diagnosis isn't clear

Fair point. My only concern is... I don't know how to tell whether the pick-n-pull MAP sensor is bad!
