Customer Concern: Came in with a broken timing belt. The timing belt was replaced and it had no spark. There is a code P0335 stored in the engine computer. The crank sensor has been replaced already. Tests/Procedures: 1. At the crank sensor disconnect the crank sensor and check to see if there is battery voltage on the Pink wire, a good ground on the Black wire and 5 volts being sent to the crank sensor.
2. Connect the sensor and check to see if battery voltage remains on the Pink wire and the Black wire stays a good ground during crank.
3. During crank, check to see if there is a 5 volt square wave signal during crank.
4. Check to see if the crankshaft reluctor wheel has been chipped, bent or broken when the timing belt failed. Potential Causes: Crankshaft Position (CKP) Sensor Harness Defective Reluctor Wheel — Bent or broken reluctor wheel.
Tech Tips: If there is a small chip, scratch or ding in the reluctor wheel, the computer will pick this up and can cause a code and no spark because the computer does not understand the signal. Diagnostic Codes: P0335

Customer Concern: The check engine light is on with a code P0335 and P1372, and the engine may hesitate at times. Code P1372 using Hyundai TSB # 02-36-014 is a erratic crankshaft position sensor signal and not a right front wheel speed sensor issue. Tests/Procedures: 1. Verify the crankshaft position sensor has good battery voltage on the Blue wire and a good ground on the Brown wire. Next the Engine Control Module (ECM) will send out 5-volts to the crankshaft position sensor on the White wire and the sensor should pulse that signal to ground. Using a scope look for a erratic or a problem with the signal. If the signal is erratic inspect the pickup wheel for damage before replacing the crankshaft position sensor.

Found the crankshaft sensor right above the starter had to take the starter off and pulled the fans off to get a better view of the crankshaft sensor.I replaced the camshaft sensor first becausr the code came up to replace it anf then the code came up to replace the crankshaft sensor when i was taking it off the wires was exposed like something had eatting through them so i am going to put the new sensor in and see if it starts ty all for the help
code 0335 bad crankshaft sensor on my 2002 hyundai sonata 2.7 i had the timing belt replaced new water pump camshaft sensor replaced and the crankshaft sensor had my coolent flushed and seen lots of old coolent still sitting by the crankshaft sensor could that be a problem for the wires on the sensor
I have the Manuals and the info is wrong. if you look standing in front of the car you will see a wire with heat shield on it, and the only way to find is to follow wire down I guess the best way to describe if you took the raditor out you could see from the front of the car by looking thru grill. 1 bolt holds on but need to use very thin wall socket to remove. not much room from sensor and bolt
Check out Hyundai factory website workshop manuals and lots of technical information is free on line. www.hmaservice.com My information shows the sensor on the 2.7L being located just under the ignition coil pack,but I don't think that is true, the only thing I can say for sure is the sensor has three wires on it.
Coolant isn't as much a concern for wiring (it is bad for timing belts and fan belts). Any type of oil is bad for wiring, fan belts, and rubber hoses. Just the heat in an engine compartment takes its toll on wiring over time. We see a lot of rodent damage, mice getting in and nibbling at wiring harnesses and hoses.
