P0107: MAP/BARO Circuit Low Input

[Smith1000]

Chris,
When you purchased yours on-line, did they ask you for the OEM off the old sensor? I was wondering if you needed to provide a specific # to get the right one for your '97 Lesabre.

I will give O'Reilly's a call tomorrow morning and see if they can order the one I need. The one I bought was $60. He said if I needed the one they didn't have, it would be $12 more. Thanks.

Does anyone know why they list 3 numbers?

Listed below are six (6) different MAP sensor brands (part numbers) and they all fit the 97 VIN (K). Notice they may have different part numbers; however, they all perform the same function.

How about adding a 7th Bo?

Wells/Duralast SU1078 available at Autozone. Around $45.00.

BTW - This brand does not having any identifying numbers just a specially sealed top with potting compound supposedly eliminating the need for a cover which is claimed to protect the internal electronic circuitry better against thermal and mechanical shocks.

Thanks Bob, normally I don't buy AZ parts, but this looks like a good price and warranty. They must be cheaper in your area!

You're welcome. Yeah Bo I know what you mean. I'm not a fan of Autozone either but in a bind I'll consider buying parts from them. Interesting how AZ's prices vary nationwide. Cost here is $44.99 to be exact plus state sales tax.

A good friend of mine that works at the nearest one by me let me take a picture of the sensor. Now you can picture the sealed top I was referring to. May be a good alternative MAP sensor but who knows for sure.

I have the BWD EC1636, which is the right one from what I have read. Thanks! The guy at O'Reilly was giving me numbers from other brands (apparently). The other part in stock was 9359409, which also would have worked. I'll install it tomorrow.

It is hard to find domestic built parts for your American built car nowadays! Even Borg Warner (BWD) has a sticker attached identifying place of origin. Notice: “Made in Mexico” is applied to all BWD parts.

Thanks Bob for taking the time to snap a pic and post it! Personally I am aware of what you were talking about when you said "specially sealed top with potting compound supposedly eliminating the need for a cover", however, for those who could not visualize this, I will provide a close-up and edited version (digital magic) of your pic for better viewing.

I got mine for $20. I think it's been figured out now, but different brands would have different part #.

Before you start replacing parts make sure your oil level us correct. The engine was overfilled by 1/16th inch on the dipstick. It caused the bottom of the PCV valve to get oily and stick due to the oil's surface pressure. As soon as I dropped out about a cup or so of engine oil and cleaned the PCV the P0107 went away. I have a 1997 Buick LaSabre. It took a while to figure this out, but I finally put 2 and 2 together and viola. Hope it helps someone.

I seriously doubt that....the fact that you had to remove the MAP to wipe the PCV valve, it could have been the connection at the MAP, o-ring out of place, sticking PCV, etc......

Sorry, but have seen the oil overfilled many times on that engine and not cause that problem....

I respectfully disagree. I changed oil on 1/7/2013 and my daughter uses this car to go to college. She's been back 4 times since and I erased that code 4 times. I replaced the PCV valve 2 weeks ago helped for about 5 minutes until the oil got hot. Today I dropped that oil out a bit and she just drove back 170 miles to college with no code showing up. That was it.

I was beating my head against the wall over this. Tried vaccum testing, checked connections, nothing. I replaced that MAP sensor 3 years ago couldn't believe it would have gone bad again.

A friend once bought a part cheaper at Autozone, took off the sticker and underneath was the more expensive brand. Of course, not everything is like that but some times it's the same part "re-branded."
