Code 0237,0112,1475,1689

[Clyde]

Just put in a new fass lift pump and vp44.

have no power.

Wont rev above 2250 RPM in overdrive

will rev to 3000 RPM with out overdrive.

really slow to get up to speed .

Not a lot of cash left to throw at the  old girl.

heart broken to see her sittin there

Did you clear the codes before the VP install and these came up afterwards? What you describe is very much like your MAP sensor has failed.

[Clyde]

Thanks for your feedback

i did clear the codes but come to think of it not after replacing the vp 44.

My code reader doesn’t work on my truck.

i had a buddy help me out before.

But with this Covid-19 I feel bad asking him to help out again.

Any advice on a cheap code reader/clearer that I can order from eBay or Amazon??

[dripley]

OBD linx lx or mx are pretty popular. You would have to google it. Most auto parts stores here rent them, not sure in your location. I just replaced my VP back in November and the MAP went with it.

[Clyde]

Thanks man

this means a lot to me.

i have a lot of checking to do.

i will be in touch when I figure this out or need some more help.

much appreciated

Should I be able to move the waste gate by hand??

i got on the ground and reached up from the bottom and with a 13/16

wrench on the waste gate and tried to move it.

it wouldn’t budge.

could the waste gate be stuck open.

The truck wouldn’t build boost then would it???

could that give me the 0237 code???

i am just a novice

what do you think?

No. It takes everything I got to just pull the shaft over the wastegate arm. It heavily sprung.

No. P0237 code is a lo volt code for the MAP sensor and has zero to do with the wastegate.This is a sensor or wiring issue.

[dripley]

I agree with Mike. You can put air pressure to the waste gate to move it.

Need 20 psi or more to move the arm.

[Clyde]

Yes I think I am up for a new map sensor.

owe just cleared the codes and ran the truck.

only 2 codes this time.

0112 and 0237.

Would I need to replace both sensors to get the truck out of limp mode.

OR

could I get away with holding off on the IAT for a little while??

short on cash right now

Thanks so much for all your help

Not a sensor problem normally... Check the OBDII codes

Will your scanner read the data from the sensors? When mine with the 237 the never changed while driving. I did not have the 112 so it could a problem in 5v supply issue as @Mopar1973Man is saying.

[Clyde]

No the scanner doesn’t read the code when driving

[dripley]

I am speaking of the data from the sensor and not codes from the computer   My scan gauge II will get a pressure reading from the sensor while driving. The numbers don't mean much  just that they are changing as you throttle up and down. When mine failed the reading did not change. 

[Clyde]

Yes I am aware that’s what you mean.

my buddy said we can try that this afternoon.

thanks again for all your help.

i will update you on our progress

[dripley]

good luck.

 

[Clyde]

Yes it was as you said.

went around the block and no change in the pressure reading.

101 kpa.

that makes me feel better.

the readings are there just not moving.

the new map should fix that.

knock on wood

LOL

Before buying a new MAP sensor, try pulling it off and spraying some wd-40 inside to break up some of the carbon and grit that may be in there.  Use some compressed air to d0uche it out real good afterwards.  I believe its a deep 30mm socket to get MAP off.

 

Worth a shot before spending $$.

correct spelling on "believe"

[Clyde]

Yes I tried this last night.

the sensor was spotless.

I did find the map sensor online for 15$ US.

so I ordered 2.

With shipping 53 US$

about 70 Canadian.

I may have to buy the adaptor cable???

thats about 80$

So all said and done about half price as what I would pay at Cummins.

OR 1/4 the price of the dealership.

thanks for your help

i will let you know when I have the new parts are installed and how it worked with the issues I’m having now

[dripley]

What kind of MAP sensor did you find for 15 bucks? And an adapter for 80? Thats the opposite of any I have ever found.
