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Rather than simply reproducing an outdated design, we partnered with an OEM sensor manufacturer to develop an all-new CPS using modern Hall Effect technology, improved electronics, and tighter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

My new favorite CPS.
I’ve tried all the common camshaft position sensor (CPS) options for my 7.3L Powerstroke. That includes both of Ford’s versions (light gray and blue with purple O-ring), and I was even considering hunting down an International one when I discovered Riff Raff’s CPS.
My engine ran decently before, but it always had a slight shimmy at idle.
• The light gray Ford CPS had the most noticeable shimmy but gave the best fuel mileage.
• The blue Ford CPS (with purple O-ring) reduced the shimmy a bit, but fuel economy dropped and it produced more smoke.
After running Riff Raff’s CPS for a while now, the idle shimmy is almost completely gone, and smoke during acceleration has cleared up as much as possible on this engine. I haven’t done long-term fuel mileage testing yet, but with the smoother idle and reduced smoke, I’m confident it’ll be significantly better than the others.
Installation note: This CPS has much tighter tolerances than the OEM versions. Definitely grease the O-ring well before installing—it still took me longer than expected to seat it properly, even with grease. That said, there’s no doubt this one seals perfectly and won’t leak.
Highly recommended if you’re chasing a smooth-running 7.3! -
Cam Position Sensor
Very impressed with the quick starts and smooth idle, I had been dealing with an inconsistent idle despite changing the usual suspects - ICP, IPR, EBP Sensor & tube, and even a new factory CPS. Still wasn't perfect after all that. But this updated CPS finally fixed this. My van starts, idles, and runs perfectly. It's really amazing and so much fun to drive now.

Upgraded cps
Another Awesome part from riffraff. Truck runs much smoother, peppier on take off too.
I’m going to get my pops one too! -
Cam position sensor
Good product made a difference in the idle and running of the engine

CPS
Worked like a charm. Solved my issues.

Best Cam sensor out there
I’ve used blue, gray, and black motorcraft sensors and I figured why not get this and put it in my 7.3 service truck, and it preforms well not failed contribution on any cylinders and seems to idle smoother ( could just be placebo effect) it just runs over all better then when I had the black sensor in.

Finally! A fix for intermittent dieing!!
After 7 years, original sensor replaced because of dieing at idle, no starts, hiccups while driving. Grey sensor lasted about 10 years, but same issues.
Engine runs much better now. Idles smooth. Starts quickly. Thank you Riffraff Diesel! -
7.3 cam sensor
Amazing!! Finally a good CPS for the 7.3 powerstroke. Engine runs and starts better. And has a much smoother idle. Big difference over the gray and purple motorcraft sensors.

Smoothed out idle
Was having a inconsistent idle and this completely smoothed it out
