this code popped up when when i started my car

what exactly does it mean and what could be the cause of it ?

also my 2 bar map sensor is not recording boost in vcm scanner, and i know that i hit about 3-4 psi of boost when i was driving the car, so why is it not recorded in the scanner

here are all the codes that i am getting

p0102
p0106
p0645
p0650
p1637
u1016
b0017
u1040
u1000

the car is running in speed density open loop mode, so if one of those codes is maf failure it is ok

also abs is deleted in the car, so that will throw a light too

 

ok i think i got the 2 bar problem figured out

can somebody help me out with the u1016 loss of comunication with VCM code ?

 

It means you either flashed or wrote to your pcm recently.

 

that's a big relief. thanks man
