Code 56 and while I was in there... - ZR-1 Net Registry Forums

I haven't had anything to share here in quite some time as I haven't had really any issues but I do login and read what others have been doing.

With that being said, a few weeks ago I got a code 56 on my 95. The FSM wasn't much help but after searching through here and some of Marc's information I found out it could be the differential pressure sensor. I want to thank Jerry for supplying the sensor, gaskets, and new PCV hoses.

While the plenum was off I wanted to replace the plastic weatherpack connector housings to the TPS, DPS, and MAP because the locking tabs had snapped off. The TPS housing was no problem to find except all I could find were black and not the orange color as original. The other 2 were a bit more difficult. The local parts stores had pigtails for $20-$25 each, but I didn't want to buy those just to remove the terminals and wires just for the $1 housing. Some of you might know of a better place, but I was able to find the correct color and indexing for the MAP and DPS from a company called Raffenday in the UK. For 6 housings (gotta have spares) and shipping came to $32. Shipping was $25...

Since I was waiting on those to show up I went ahead and blocked the throttle body coolant, added a PCV oil catch can, and removed the secondary vacuum parts and safety wired them open. Everything I've read on here was helpful in that and I want to thank Marc for the upgraded calibration chip. I had everything ready to go and the chip showed in the mail today. Got that put in and have only had a chance to drive a few miles and not really open roads. It's been a while since I've driven her but I plan to change that in the next few days!

Again, thanks to all of you who have provided information on here!
