On stsrtup as you try to start car it trys to turnover and may take about three to four goes before it starts then the engine light comes on and stays on for a while until its clears itself after a few restarts of the engine. It spit and backfired a few times after we started it. I've followed through the wiring and see nothing out of sync. Is the resistance below 3. I got the code reader and saw the P0339 and replaced the sensor. Also, engine vibration could work something loose. Can the cranck shaft cause the car to loose power after it warms up? The crankshaft sensor is often fitted at the front or the of the engine.
Then replace the engine wiring harness. You might find an open circuit or a bad connection somewhere. Road tested for half an hour. The change in the magnetic field cause the voltage from the sensor to change. How serious is the P0335 code? Visually inspect the sensor mountng location for damage, foreign material.
Check the vehicle repair history Step 5. I created this blog to share the knowledge I have collected through the years, and I hope that you will find the information helpful. The is the place where the industries best transmission rebuilders work together to help solve the most complex automatic transmission problems. Look up the other , please use the search box. This information is used by the P0339 code. Honda Accord P0339 if your catalytic convertor fails completely, you eventually won't be able to keep the car running.
Obviously, timing is everything and, in the modern engine, timing down to the millisecond is absolutely essential for proper operation, power delivery, and fuel economy. Read the article and I will explain how to diagnose it properly and repair it for the lowest cost. Low voltage can give you false results and even damage your control units. The solution is here : Honda Accord P0339 Possible Solution : Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Your problem could be something else, Is the check-engine light on? Check the wiring harness for damage. I also have a Kia Cerato 2008 and what happens is that it start normally and after a a few minutes of driving it starts to loose power no mater how much gas i give it.
I live in Sweden, and I have been working as a mechanic for over ten years and are a specialist and certified in automotive diagnostics. The small ones look like a bit smaller than standard trailer light wires when I compare them to the trailer wires I have and the black one is probably 3x the small ones. So you should chech it on our car models. Check the 5-volt supply circuit voltage Step 6. I didn't find anything online about a signal plate. The currently selected is for the Chrysler makes.
If you get the correct value, measure the ohms from the engine control unit connector with the sensor connector plugged in. I have checked the signal at the crank sensor and at the com. Once this engine was put in had intermittant running rough condition under load and heavy accel and has code po339. Did it again at 45-50mph and did not happen again during this time vehicle did not lose power and acceleration was fine. After replacing the sensor and wiring harness, perform a crankshaft position sensor clear and relearn procedure. Sometimes if the , flywheel or internal trigger wheel gets faulty, it can damage the crankshaft sensor and make the engine control unit to trigger the P0339. The change in the magnetic field cause the voltage from the sensor to change.
The can also be fitted to your engine block and read the signal internally from the crankshaft inside the engine block. Common mistakes when diagnosing the P0335 code Even with experienced technicians, mistakes can be made when diagnosing any code if they do not follow all diagnostic steps in the proper order. If damage is noted or loose connections are found, these must be replaced or repaired. If you replaced the sensor and it was ok for awhile, then came back as intermittent maybe the sensor was not bad and the problem is in the wiring or connection. I'm the writer and the owner of this website. It can also be fitted at the front and read the signal from a trigger wheel See picture.
Check the repair manual for the correct Ohm result. Same when driving only at lower rpm. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In any case, I would start with checking all the fuses. Hoping code wont reappear after the expense! The changing gap causes the magnetic field near the sensor to change.
