Today, hopped in the lib and while heading up a hill, no power, flat land, no power. I didn't notice any smoke.

codes that are popping are p0107, 0113 and 0110

any guesses?

Thanks!

P0107 MANIFOLD ABSOLUTE PRESSURE SENSOR CIRCUIT LOW.
P0113 INTAKE AIR TEMPERATURE SENSOR CIRCUIT HIGH.
P0110 INTAKE AIR TEMP SENSOR SIGNAL VOLTAGE to high or low

I'd:
1. check for a clogged air filter
2. remove both turbo>intercooler>engine hoses from the vehicle; take off the woven covering if on the hoses; and carefully check the bottom for holes, tears, soggy with oil spots - this assumes you don't have new OEM hoses or Samcos, if you don't and the hoses you do have are intact but oil soaked they need replacing even if they don't have holes/tears.
3. while these hoses are off see if the airbox to turbo hose is torn just in front of turbo (dealer only for replacement cost ca. $60).
4. clean your MAP sensor - read Sir Sam's NOOB guide for instructions and other helpful hints.

My first bet is #2. Happened to a local friend; no power no smoke nice hose tear.

If there's no smoke when you try to accelerate I bet your MAP sensor has just flat gone bad. Esp with those 3 codes.

Aren't these two codes to do with that little "Mercedes Logo" sensor on the air box near the MAF sensor. I recall people having problems if it came loose.

well, it may be the sensor. I did discover the airbox to turbo hose is ruined per the usual stuff.

I'll start with a hose...go from there.

Thanks

are there part numbers for that sensor?

The extra sensor on the airbox is for atmospheric pressure, not temperature, so I don't think that would cause it. The MAP is a combination pressure/temp sensor.

Also matt, if the hose between the airbox and turbo is partly torn, it doesn't throw any codes. See following link for part numbers viewtopic.php?f=5&t=54092&p=603314&hilit=numbers#p603314

It doesn't always make sense - but we are talking about a computer - and people have had problems with it.

True that.

Check all the sensors you can find in the engine bay to make sure the connectors are tight.

new turbo hose will be in tomorrow morning. Just on a whim, I decided to clean up the map sensor. the plug was definitely not tight. Here's to crossing fingers! :lol:
