What is the size of the socket used to remove the IPR valve?

 

35mm......

 

But it takes a special socket with a slot cut out of one side available from Lisle for about $25.

 

 

yeah I knew it was a special socket, one that has a slot on the side to go around the connector. I have a 35mm socket and a mill here at work so I am going to make one, question is how wide is the connector on the IPR valve or if anyone has one of these sockets how wide is the slot.

 

Hope you can read upside down.

 

My socket has an aprox. 23mm cut out.

 

thanks for all the great info guys

 

is there a wiring harness or pigtail I can buy to replace the connector on my IPR valve?

So I took off my ipr valve and noticed the screen was tore, I replaced the screen and put it back in and still no start. I spoke with a guy and he said I need a new ipr and oil cooler, my question is do I really need an oil cooler? I don't have a scan gauge so I can't check live data. Is there a way to check the ipr outside the truck? Pulling my hair out here. Going camping next weekend and the thing up and running but don't really have the $$$ to throw 3,000 into in at a shop

 

Take your ipr back out. Remove the screen and under that is large brass plunger. Press that in and flush with carb cleaner. Then while holding the plunger in blow out with compressed air, sometimes that works. You need to remove the oil cooler and check the hpop intake screen. When I had repeated ipr failures it was from a torn hpop intake screen.

 

You really need an OBDII monitor to do much. If you have a smart phone or a laptop there are some surprisingly inexpensive options. Check this thread for more info.

You can see what your ICP is reading with these instructions below. Remember, what you read with the meter will be what the sensor thinks the pressure is, it can be wrong if the sensor is bad.

Alternately, if you unplug the sensor, the pcm sees the open circuit and supplies a default value that will allow the truck to start IF there actually is sufficient pressure to operate the injectors.

Here is a way of checking to see if you have sufficient high pressure oil without having a gauge or adapter. Strip back the wires about an inch away from the icp sensor connector. Obtain a digital multimeter and set it for voltage (DC). The bn-wh wire is a five volt reference, leave that alone. Strip back the db-lg signal wire and the gy-rd ground wire. Put positive lead on a dark blue-light green wire and negative lead on gray-red wire. Have an assistant crank truck, you need a minimum of 0.82 volts (500 psi) for the truck to start, if you are getting greater than that then you have sufficient high pressure oil.

 

I have the sct tuner, can I use that to get data?

 

Some STC models have gauge features I believe, and some are just tuners...
