Just put a motor in and three days later (180 miles) i'm getting this ecu code. Can anyone tell me where this sensor is? Thanks in advance!

 

I believe it is your MAP sensor. It's either on your firewall or on top of your throttle body, with a three wire harness. HTH.

The barometric sensor is in the ecu. Reset the ecu and hope it doesn't come on again. If it does, check the voltage coming out of the map. At atmospheric, it should be @ 2.8-3 volts. If the map is not around that level, the ecu may think it is the internal sensor.......HTH

 

the ecu is usually very good at differentiating between the baro and map sensors.
Try replacing the ecu.

 

What year car is this for? OBDI code 14 is the IACV sensor

 

good catch val.

for pretty much every year afaik(88+ for sure) 14 is IACV

 

I should know...

I popped the code last night, the car bearly idled...I was like WTF?! I checked and the plug came loose from the sensor

 

doesnt matter. same code.
all the codes are the same from 88 and on, they just added more numbers
