CPS Tester

Being a gear head I tend to buy tools just because I like the way they look.

Now I am seeing an OTC 303-1134 advertized on ebay as a Ford 7.3 PS cam position sensor testor.

Anyone have any experience with this tool to give me before I go after it?

Also I have read about a turbo boost leak detector, What is that all about?

Thanks

To be honest, I don't know if it's worth buying a tester for the CPS. Generally they are either good or bad. No in between. And for the price of that tester, you can just pick up another CPS and keep it in the glove box in case yours goes out.

Here is a picture of the boost leak detector I built.

A 3" pvc cap drilled and tapped for air tool quick disconnects and a pressure regulator. Got it all, except the pvc cap, at Harbor Freight for a few bucks. The gauge on the regulator is not very accurate but my boost gauge is. Just unhook your air filter and clamp this puppy in there then add some air. Get a squirt bottle with soapy water and start spraying all connections. I just set it at about 5 psi. Soap up everything on the intake, my AIH plug was leaking.

Boost Leak

Thanks for the info. I can make one up and check out my E99. As old as the system is , it is bound to have leaks.

A CPS tester is like a blinker bulb tester. Would you buy a $5 tool to test a burnt out bulb?

Testers may not be effective for testing a currently used component; however, having a CPS tester or bulb tester may come in handy if you have a tendency to have a large amount of extra items or come across an old “keeper” and you can’t remember where it came from or if it is still good. Much easier to test it than to take the good one off the truck and install the questionable item to see if it works. Personally, I don’t have a large amount of parts laying around except for a few important spare items that many carry on a daily basis. If you have the extra money and you like to collect every possible tool out there, go for it. You may only use it once or twice every 10 years or so but the choice is yours. I am sure all of us can go out in their garage and point to an item that we thought we needed and it has yet to be used even after many years.
