Riffraff Diesel Cam Position Sensor CPS 1994-2003 7.3L
The Cam Position Sensor (CPS) is one of the most critical sensors on your 7.3L Powerstroke. It provides the PCM with engine crank position and speed information, allowing the injectors to fire at precisely the right time. When the signal becomes weak or erratic, it can lead to poor drivability, intermittent stalling, hard starting, or even a no-start condition.
The original International “Black CPS” earned a loyal following among 7.3L owners for its excellent drivability and throttle response. When it was discontinued, many aftermarket replacements failed to deliver the same consistent performance.
Rather than simply reproducing an outdated design, we partnered with an OEM sensor manufacturer to develop an all-new CPS using modern Hall Effect technology, improved electronics, and tighter manufacturing controls. The result is a sensor engineered to provide exceptional signal stability, outstanding reliability, and the smooth performance 7.3L owners expect.
Every sensor is manufactured in an IATF 16949 and ISO 14001 certified facility, individually tested before packaging, and validated on an actual 7.3L camshaft gear to ensure consistent performance right out of the box.
Whether you’re replacing a failed sensor or upgrading from an inconsistent aftermarket unit, our Upgraded CPS delivers the quality, reliability, and confidence your Powerstroke deserves.

Do it
Had truck for about 6 months, never messed with CPS/no issues with it. Replaced it with this 1. To get the experience of changing one out and 2. Because I was unsure of the age / make of the current one. What a difference! Did this the same day as plenum boots and inserts which gave me some power back but there was absolutely a noticeable improvement in the way my truck started and ran. As a side note, the one I pulled out was a no-name that looked very old

RiffRaff cam position sensor
It works exactly as described. Ran a contribution test before and after. Considerably more equal across the board. Truck starts quicker and runs smoother at idle.

New technology makes a difference
My 99.0001 F-250 always loped after I let off the accelerator. This higher-quality, newer technology sensor resolved that issue.

RiffRaff CPS upgrade unit
Impressive. Quieter and smoother running engine in my 246k mile 1997 7.3 PSD. Worth every penny.

CPS?
Big improvement on starts. Romps soon after the key is turned, eliminating longer turn overs. Very happy with it

The long waited update we have been needing!
It is well worth the wait time for the production for these! Installation is a breeze, and results are instant. Right away in starting, it took less then 3 revolutions on the cranking for start up in cold temps for fire up!
On idle, far smoother then OEM! Keeping idle dialed in right at 750 with no engine harmonics distorting. As wild as it is, it quieted the engine considerably! I have always wondered what a 7.3 sounds like without the normal injector tapping on idle... Now I finally know! It sounds and feels perfect!
Throttle response pepped up! Take off from a stop is much nicer and quicker! On top of quicker acceleration, the pick up follows all the way through. The best way to describe it was the load you have on RPMs increasing speed suddenly, the turbo seems to time a lot better with the throttle load, no delay in beginning spool up, as if the PCM gets a clearer signal to roll the boost faster.
Any random injector misses dissapear all the way through acceleration. I have to find out the fuel economy benefits, but as for now driveability just becomes far more pleasurable and modern! -
Riffraff CPS
Installed this CPS along with the HPX and FRX at the same time. My truck runs quieter and smoother! After reading a few reviews about the CPS being difficult to install, I made sure the o-ring was lubed well, got it started along with the bolt and slowly tightened the bolt until CPS was fully seated. Easy install. The previous CPS was the black with purple o-ring and I pushed that easily in by hand. Haven’t been able to test if there is a fuel mileage difference yet.

Cps
Didn’t see any difference when putting the new one in.

Riffraff cps
Truck had no issues to begin with other than old cps o ring leaking and runs great with the updated cps also. Using the old one as a spare. Time will tell, but am sure it will outlive me
