Question: I’ve noticed different crankshaft sensors on 2.7L Hyundai engines. Is there a revised sensor, and if so, which one should I use?

Answer: The AERA Technical Committee offers the following information regarding a revised crankshaft sensor for 2001-’02 Hyundai 2.7L engines. Since this engine was first designed, three crankshaft sensors have been used. The original design sensor should no longer be used. To help determine which sensor is appropriate for use, Hyundai has supplied visual aids for positive identification. Refer to the photos at left and part numbers below to select the proper crankshaft sensor. The current sensor has two different designs.

Part Number 39180-37200 (Photo 1): Inspect the CKP sensor. If the wiring of the CKP sensor comes out straight from the top of the sensor, replace the sensor.

Part Number 39180-37150 (Photo 2): If the wiring of the CKP sensor comes out at a 90° angle from the top of the sensor, do not replace the sensor.

Part Number 39180-37150 (Photo 3): If the wiring of the CKP sensor comes out straight from the top of the sensor and has a 90° plastic knob at the top of the sensor, then do not replace the sensor unless it is damaged.

With the complexity of today’s modern vehicles, as technicians, we are going to have to stay on top of our game.

Over the last 28 years of being a technician, I have developed the habit of checking for and reading technical service bulletins at the forefront of the diagnostic process, especially when an unfamiliar vehicle exhibiting blatant or straightforward concerns comes into the shop. I have found many valuable nuggets of information while reading over these bulletins, from wiring concerns and connector issues, to transfer noises, water leaks, and engine and transmission performance concerns. The knowledge gained in reading through these bulletins has not only helped me with the vehicles I’m working on, but also increased my perspective and ability to connect the dots on other vehicles that don’t pertain to a current bulletin.
