i cleared them again and did a self test with my boys computer

P0243 Wastegate Solenoid A Malfunction
P1780 Trans Control Switch (O/D Cancel) Out of Self Test Range

 

Wastegate Solenoid A

what is that?

 

You need the letter P or b or whatever to be sure thats the right code.....

Wastegate is typically on a turbo

HOW DO you do a self test?

 

it was on his scanner

said to start the engine, and it was messing around the engine, reving it up and checking all kinds of sensors


pretty neat scanner

 

do you have an oil breather cap??

 

nope

 

Do you have a K&N filter? If so, the MAF might be contaminated from the filters oil. This happened to my truck, and the MAF had to be replaced.

 

yea i have a k&n


but its a brand new filter

does it come wit oil on it already?


i also just pulled 2 spark plugs

they look normal, no signs of detontion or running lean

 

how do you test out if the maf is fine or not, is there a voltage test?
