Mercedes Benz W202 Bad Throttle Postion Sensor/Signal
zhlédnutí 15KPřed 9 lety
Here's an example of a BAD throttle position signal on a Mercedes Benz W202 Engine, C-Class model. -Clip shows a TPS signal that is only capable of sensing a 2% & 11% value on a potentiometer type component. -I am using the BluePoint MicroScan Tool to confirm data. -I also could have used an Oscilloscope to zoom in on the signal(but this was sufficient). -This Video Shows The Internal Component...
You have to get that cutting tool more into the tool head hanging out way too much. I think you need to spend a little bit more time centering little bit also. Also, I find things like chrome, Molly sockets and those cheap welded carbide‘s that come with your lathe need high spindle speed. Also take a fine diamond file to the edges of those carbide tips. Will help cut better
Uhm... ive never seen it done like this...
To start with, learn how to use a lathe correctly. Plunging that bit is unnecessarily stressing the machine. Should have started the cut past the end of the socket and cut towards the chuck.
I admire your understanding of the TB system. Thanks for posting this video on youtube.😊😊😊
Bro tried to indicate a 3 jaw chuck
Joe Pie even indicates when using a 3 jaw chuck.
What's the point 😢
My thoughts exactly....
I’ve had to do this. Some sockets have thick walls that won’t let you get in tight areas
@@cuztanksrule4774 yep, as a 35 year auto mechanic I’ve had to customize many sockets. Usually just use the grinder though. Didn’t usually have a Lathe on hand. Looks much better using a Lathe. Although I recently got a Lathe a few years ago and it’s been real fun. I finally got to fix a coolant temp sensor socket that was not board big enough to fit over the plastic electrical plug finally got that fixed.
Choke up further on the tool it will feel,look and sound much better. Short and rigid
Can that worn spot be changed moved more up or down without affecting throttle idling?
Nice video !! I have a USA version 1994 C280 Benz. The cars idle has become very erratic. At stop lights, while in drive, the car engine revs up and down as if you were trying to tempt the car next to you to drag race. Once you accelerate away from a stop, the car drives perfectly, accelerates great, and no other known problems. I believe the throttle body or throttle position sensor is at fault. I wonder if you have an opinion?? Because the car is pre OBD2 I don't think scanning the car's computer will yield anything. Were you able to find any internal components for your position sensor to repair yours ?? Thanks !
Same case here... mine is C180 W202 pre obd2.... any update on the fix?
update on my fix (i dont know when it will last... lol) i suspected that the ECU is trying to compensate with some logic on it, and it seems related with the air/fuel ratio... so what i did was simple turn the CO potentiometer clockwise around 270 degree and making it running more lean. I also fixed some small air leaks into my throttle body :-D. And of course resetting the ECU is needed by simply disconnecting the battery and reconnect. Hope this help... :-D
@@Wu11er fixed?
@@mercow1242 yes it worked for me. But ever since I've overhauled my transmission (722.4), this problem never show up. Fyi, my 722.4 was near totaled, thank God I've overhauled that just before it destroyed :lol:
I need wiring color combination i have black, brown, red, white, yellow, grey, green , red brown, in throttle actuator but in my engine connector harness there is black, white, yellow, brown, blue, purple, red brown, red. I want to connect it proper let me know which of these wires colors correctly.
Is there a certain code you get?
W202 is the chassis code, not the engine. Can't really tell but it looks like an M104, but definitely not a W202 as there is no such engine.
hugeshows Thanks for mentioning information I already know!
i didnt think this scan tool worked on german cars? thats good to know.
you can just bench test it with a multi meter they have the pinouts on the forums. I just rebuilt the wiring on mines bench tested it. I will have it put in my car for final testing.
Or Simply Use A Scan Tool.lolThere Are A Variety of Options. Multimeters are extremely slow at showing accurate data like a Throttle Position Sweep, Which can easily disguise a true fault,or dead spot.
Old Tool, But It Continues to put in Work.
