My Hyundai Tucson is showing the P0113 and P0108, what could be the reason ?

The car transmission and overall performance of a car has been terrible . The turbo seems not to function.

Today after a hard acceleration I get error 0234 "pending" and I my car go to lim mode . After few investigation I find a bad PVC valve and oil on throttle body. That lead me to remove the map sensor for inspection and it was full on carbon deposit. I clean it and 50km now I didn't had any problem except my I idle drop little bit 680rpm from 730rpm .

My ford ranger 2.2 diesel 2016 model, used to just turn itself off while on the move. What couses this?

I have a similar issue on my 2010 scirocco. The sensors unplugged and it’s causing the car to become unresponsive when hitting for throttle now and again but when plugged in it feels like the cars trying to break my neck would this be a dodgy map sensor

There is a ghost in my machine. 95 Buick LeSabre 3.8L. Engine light comes on. Connector is OBD2 but the guts are OBD1. Do I need to have a Tech 2 to check for codes? OBD2 couldn’t read it. 🤷‍♀️ My guess is she’s got a bad MAP sensor. Tried d/c battery, got the light to go out for about 10 seconds until the idle got rough. (I’m not a mechanic. I did rebuild my ‘68 Camaro 327 back in the 80s) but this is beyond my scope of pantyhose and baling wire.

I’m getting false p2173 (vacuum leak) and i’ve checked the vacuum line and its air tight, could this be a bad MAP sensor?

[chaoticlizard]

Could it cause service trans, anti lock system and traction control warnings?

I have a 1992 ford f150 standard transmission and the rpms surge to 3000+ rpms. Continues to surge when in gear, making it very hard on my brakes going over mountian passes. I Cleaned the trittle body and replaced the air pressure control valve. It helped but it still surges, would the MAP sensor be my next part to look at?

My car won’t start if my map sensor is plugged in and when I do start it with the map
Sensor unplugged it has a rough start. Has any one ever seen this before?

[astridaberzina]

No check engine light 💡 comes on —I have to pump the gas pedal a few times for my truck to start if I don’t it won’t turn over 2. It kill’s while I’m driving —- someone in the comments help me out 🙏
