The dtc 71 came up on the datamaster, and that is the a/c evap sensor failed. How hard is it to replace this sensor? If anyone knows where I can find a step by step, that would be very helpful.

 

what are the symptoms of this?

 

No cold air blowing out. We recharged the a/c, and checked everything else. I thought at first it had something to do with the wiring harness, because there was no service light wasn't on, and I hooked the datamaster up to the car, turned on the a/c and this dtc 71 came on. Says it's the a/c evap sensor.

 

compressor is kicking on right? and did you replace the evap sensor?

 

I didn't replace the evap sensor. That's the error I am getting and I'm wanting to replace. Is it hard?

 

If you are refering to the a/c refrigerant pressure sensor it is located in the a/c line from the evap to the dryer...just unplug the connector and unthread it...the part number is 22664328 $55.45 Canadian...hope this helps...

 

The evaporator sensor is stuck in the fins of the evaporator under the dash. Heck, it might just be unplugged.

 

I might have a pic of the location, I'll look

 

That would help alot. That could be it. Is the plug wire a part of the wiring harness?

 

It plugs into the harness that comes from the computer. (remember, you can click on sections of that pic to zoom in)
