Dull Men's Club
An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

I swapped one of these on an old Kia once. Dealer wanted over a hundred for the part, but I was able to get an OEM part on ebay straight from South Korea for less than twenty bucks shipped. IIRC, the hardest part was disconnecting the wiring harness on the old one. Like yours, it took a while to figure out what was wrong with the car, as it didn't throw the expected code right away. It just suddenly started running poorly. I think it's mostly for optimisation, and the basic timing works well enough from physical position, else my interference engine likely would have blown itself up at some point.
Yes indeed! Ours is a 2005 Hyundai Tucson, 6 cylinder 2.7L, much props for recognizing the part without full context, but yes it's compatible with the Kia Sportage of about the same year range. 👍
By the way though, the CKPS only affects the electrical timing of the spark plugs and the fuel injectors. The timing chain affects the mechanical timing, separately, but in time nonetheless.
Sorry it might be difficult to explain, but the CKPS ain't got shit to do with an interference engine, that's all on the mechanical timing chain side. This was all on the electrical timing side from the faulty CKPS.
But the CKPS is absolutely important and necessary to detect and send the timing signals to the ECM to send the signals to the spark plugs and fuel injectors.
Bad CKPS means no spark and no fuel.
Yep, I had a 2002 Kia Rio and the part looked familiar when I scrolled past! What I meant is that I assume the mechanical timing still permits the electrical timing to function without the sensor, it just isn't firing optimally. If it was completely dependent on the sensor for firing the plugs, I figured it would either not run at all, or worse, cause a bad enough misfire that could do some cylinder damage. Though maybe there isn't a bad enough misfire to do that? I don't know enough about them.
I also had a 2007 Sonata that blew up a few years ago when the timing chain broke, so some experience with failed mechanical timing too :) That was a great car I wish I'd tried to rebuild the engine on, but I just downsized to one car instead. Good luck with your Tucson! Good to see the older cars still ticking along.
Our model's CKPS is apparently entirely in control of the spark plug and fuel injector timing. Though obviously not all vehicles are designed that way.
When the sensor totally failed, there was no spark or fuel to any of the 6 cylinders. New sensor got it back running 👍
As far as the timing chain, that's on the other side of the engine on this model. The timing chain is what physically keeps the crankshaft in time with the valves, totally other part of the system, but still closely related.
