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Rather than simply reproducing an outdated design, we partnered with an OEM sensor manufacturer to develop an all-new CPS using modern Hall Effect technology, improved electronics, and tighter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.

Not Much to Say
Pretty much same as everyone else, smooth idle and much quieter running overall. Could go on, but it is exactly like they shown on the graph. Great improvement overall.

Satisfied!
I’ve put only about 100 miles on the truck since installing the new CPS. But the truck noticeably starts quicker and runs smoother. It also feels like the power is better, and doesn’t lug as much when RPM’s are low. Another thing I am noticing and will keep an eye on is the oil temps appear to be down about 5 degrees under the same conditions. I will try to update as I put more miles on the truck with the new CPS.

Riffraff CPS
I was definitely a little skeptical if I’m being honest, but after installing the upgraded CPS my truck idles better and is quieter. I can’t notice a difference driving but having the smoother idle is a big plus. I will absolutely be buying another one.

Riffraff Cam Sensor
The Riffraff can sensor resulted in very violent engine stop/start incidents. I verified it was installed all the way in. I was surprised how violent these moments were. In the first test drive, was driving fine then, the engine would momentarily shut off for a half a second or so then come back on for another half second, and continue this cycle slamming the transmission. In 30 years of working on cars and truck it was the most violent thing I’ve felt from an engine even more than when I felt a crankshaft break. I installed a Cam sensor from Ford and no problems since then.

Smooth Idle
Way smoother idle and this truck has never passed a contribution test till now. Very happy.

New CPS
Came well packaged and a day early. Easy install, probably easiest to do on the whole truck other than the IPC sensor. Overall everything seems to run better, just like when it was new with my old black ford CPS. Worth the money.
-
CPS
I couldn't get new part to goes in the block because of the O-ring. I tried to use even a bar to pry it but thought it was going to break. Only way to get it in was use my old o-ring. Defuse not feel any difference in running at all and still fluctuating on tack still. But will see how it lasts.
-
Best CPS
I was doubtful that after all these years that a better sensor could be made, but I was wrong. My truck starts faster, smoother idles, and I would swear better throttle response. Very happy with this sensor and I will be getting another just to keep in case.

I think the truck starts better
Easy to install
