you have to be a tech to own a scanner ?? and yes iam a tech a body tech i do paint body and customizing ..when it comes to emissions i dont have a clue i usally rip it out and plate it in another county..lol but that is not going fly this time.. and yes i said cleared the codes... not unplugged battery.like i said..
"i cleared codes the other day by resetting the egr by unplugging the egr valve turning key on cleared the codes then turning off ignition right away then plugging egr back in and starting the car.the code was gone and stay gone "
cleared the codes meaning i turned the key on and cleared the codes right when the scanner say codes cleared turn the ignition off
i found this online somewhere and suprised when it actually work for four days and then popped up a new code
and it did clear the code previous code was a p1440 i believe and now its gone but two new ones popped up..after 4 days of long drives and also city driving about a tank and half of gas.
This scan tool should be able to tell you EGR pintle position and commanded position....yes i checked it out iam not awesome with the scan tool but it showed me a -14 % ...meaning what??does that mean ecm has to be reflashed have u heard of this?
as for gas cap old one was loose as a lot lizard thats y i changed it i have indeed looked at it and no corosion nor was there and damage to any hose that i could see or find.
