I feel your pain. The general concensus.. ECU is crapped out

 

Hey Joel. Code 13 is Barometric pressure sensor. It measures atmospheric pressure. I think it's your ecu is acting up for whatever reason. If you can get a hold another ecu, swap it out and test if for few days.

 

Supp Ray...are u talking about the stock ecu or my greddy ecu...but for some reason im getting it only like once a month...i hope whatever the reason is not something serious...i really wanna find out the cause of this...thanks again

 

Stock ecu. There's a sensor circuit that is inside the ecu and is built in.

If it's intermittent, then your ok for now since it only comes on a month later.

Try this test. Reset your ecu one more time, hold the rpms to 3k until you hear the fan comes on, let it idle after, go for a test drive in 3rd or 4th gear on WOT for 5 seconds (this will take you up to 100mph. just be careful). If it does come on, then we have an ecu problem.

 

just for kicks if it is a greddy turbo installed 13 has a problem witht heir blue box. greddy knows this and many greddy turbo owners throw a 13. To combat it for me warm car to normal operating temp then drive. The problem is when yo don twarm up the car and rev at a low rpm in like 2nd gear or such it throws the code. Been through it with greddy many times.

 

Not for me, I don't have a blue box, just a lovley CEL showing me a code 13

 

u are absolutely right..it comes on when sometimes cold start...or when i shift it to second gear and when i go to fifth gear at a speed of 20mph or 30mph...dont know y but what do u think should i do with this...do u think that its the greddy blue box then...thanks bro
