Standard Motor Products PC684 Crankshaft Sensor

Here is my experience with the random engine shutoffs: vehicle is a 2012 Jeep Patriot Latitude 2.4L 4x4 with manual transmission. I started to have random shutoffs while driving. It usually happened while accelerating to city speed, typically around 3rd gear. The dash would stay lit up, radio stays on, but RPM's dropped to zero. The first few times it would start back up while still moving, after that it would need a few minutes to cool off before starting again. The check engine light came on the first time and stayed on for a few days before clearing itself. After the first couple shutoffs, it would not stay on for more than a key cycle. It did this about ten times over a roughly two week span.I took it to a parts store to get scanned, and it showed about ten codes, about 5-6 different ones. One of them that was repeated that caught my eye was the crankshaft position sensor A circuit malfunction (P0335). Got one of these, threw it in, and three weeks later it hasn't cut out on me even once.The installation was easier than expected, but I do consider myself decently handy working on vehicles. I had it installed and reassembled in about an hour. I did this by disconnecting and removing the battery, removing the airbox (and two large electrical plugs from it), removing the exhaust manifold heat shield (after the vehicle has had plenty of time to cool off since moving), and then removing the smaller vertically-oriented heat shield which is held by two bolts and one nut on the rear of the engine (driver side) to find the crankshaft position sensor underneath. There is a wiring harness leading down to the crankshaft position sensor--I believe this is also connected to the camshaft position sensor that is much more visible and accessible.The crankshaft sensor and the heat shield covering it come off with 10mm and 13mm sockets. I don't remember which I used where, but if you're doing this job you should already have both 1/4" and 3/8" drive metric socket sets with extensions and at least one swivel which you may or may not need. These bolts are awkwardly positioned and will not find an easy way to see them. You will have much better luck if you are capable of finding your way to the bolts with your fingertips. After you get the smaller heat shield off, the sensor is accessible to unplug easily and is removed with a 10mm socket.I have seen on forums a lot of mention of relearn procedures, which involved accelerating to 70mph and then allowing a free coast to 40mph, and then repeating the process. I am not qualified to say if it is actually an important step, but strictly anecdotally speaking, I have not noticed any difference in vehicle performance by skipping this.TL;DR the part works well, I am satisfied. It was moderately challenging to install.

If you replace this part in the same vehicle, you will need to drive the car for awhile afterwards (about a week…depending on your driving style). The engine light on the dash will remain lit if you don’t, even after clearing the trouble codes. I tried to find an OBD scanner that was reasonably priced (under $350) but none of them could relearn the settings to clear the code. Many claimed they could relearn camshaft sensors on this car, but after communicating with various companies, they could not do this year, make, and model. To do it without a bidirectional OBD scanner, you need to use other other OBD tool functions and go through a bit of a complicated and time consuming process. I hope this info is helpful for someone having to deal with this on your Caliber. Note: they discontinued the production of these vehicles for good reasons. Happy wrenching to you!

Purchased this as an inexpensive solution to my 2016 Jeep Patriot with a stalling issue that was getting worse as time went on. Looked exactly like the one I removed. Time will tell, when it comes to aftermarket products, how long this part will last. But for now, solved my problem so I recommend it.Update 11/2022This crankshaft sensor lasted only 2 years. As a result, I purchased one from my nearest AutoZone store. Although I paid more for the AutoZone part, I'm hoping it lasts longer. As a result, I'm bringing my rating down to four stars.

The product was perfect. It was for my 2007 dodge caliber and the price was affordable. Thank you so much. I recommend people to order online with Amazon. It was a pleasure doing business with your company.

Went out after 2 months and had to replace it again.

It fits and it works

After talking to a few people and them getting the cause of my car issues wrong my bro in law told me to get this. So far, so good. No issues and it’s been about a month.Update: had to buy another one after a little over a year... it died on me again. Decided to buy from the manufacturer— mopar parts. Since I could not get in touch with anyone about the original part I bought from here. Amazon told me to call but the number was out of service to the guys that make this one, therefore leaving me no choice but in having to go back to mopar.

El producto llegó rápido y muy bien, Excelente...!!!
