It's still hissing when the engine is idling, you just can't hear it.

both sensors are new
both temp sensors are new
just replaced them. then I got the code.

no, I hear air hissing sound (fairly loud when I try to start. it does start but takes several seconds of cranking) . it might stall as I hear the hissing while it's trying to run. then the hissing stops and the truck can be driven. when it is at operational temperature it will not start again until it cools off some. about 20mins.
but, I can hear the hissing then hear it stop. it sounds like the hissing is on the passenger side of the engine.
is there a diagram that shows this sensor. I'm a diy-er but, not real saavy on terminology.
