Here is another interesting case from practice.
The client complains that the motor does not start. But sometimes the car will stand for 1-2 weeks and then start again. If the engine starts, it works well, but it is worth turning off the ignition and not starting again for 1-2 weeks.
The client brought the car in for repairs. With difficulty, he started the engine near the house. After entering the rembox, I turned it off and the engine did not start again.
The client himself sinned that the immobilizer was faulty and needed. According to him, the keys were already prescribed to him in another car service, but it did not help. From this I concluded that the problem is not in the immobilizer. I connected the scanner, looked at the errors. Everything was fine with the immobilizer. All keys are trained and the system accepts them, the block is trained. Conclusion: the immobilizer is working.
There was only one error on the motor: 0335 - the crankshaft position sensor (DPKV) is faulty. I removed the sensor and measured its resistance. It equaled infinity. But if you heat the DPKV with a hair dryer, then the resistance begins to appear from a value of 1 mOhm. It is clear that the DPKV is faulty and needs to be replaced.
The case is quite typical and I would not have written about it, if not for one "but" ...
I give the client the removed DPKV and ask him to buy exactly the same original sensor. I myself am already in anticipation that I will quickly make a car and it will leave me in an hour. But it wasn’t there… A client comes, brings the DPKV. I ask:
Original?
No. But good!
Just in case, I check the resistance of the new sensor - 260 ohms. Order! I put the sensor in place, turn the key in the ignition to start and ... the engine does not start! There is fuel injection but no spark. I reconnect the scanner. The same error 0335 - the DPKV is faulty.
And that's where it all started! . It got to the point that I replaced the regular ECU with my replacement one, but this did not help either. All signals are there, everything is in order, but the engine does not start! Miracles!
"The hall's help is required," I decided. I call Sergey Gazetin, explain the situation and we come to the conclusion that it is necessary to swap the DPKV wires. I swap wires. And here it is the moment of truth: the engine started with half a turn!!! Eprst ... I jumped around this car in a cold rembox for two days, caught a cold, fell ill, did not sleep for two nights from coughing and fever, and only because of a non-original, Chinese sensor.
P.S. In the text, I highlighted the word original sensor for a reason. I specifically focused the attention of the client on this, gave him a sensor, but unfortunately he missed my words on deaf ears.
Hyundai Elantra has become popular car behind last years. Its low cost with good operational properties increased sales several times. Driving the Hyundai Elantra is easy and modern style And elegant design makes this car a worthy representative of its class.
- Maintenance
- Diagnostic Trouble Codes (With system on-board diagnostics, Without OBD system for 1.6l and 1.8l engines.)
- Troubleshooting Examples
Maintenance
Despite the reliability of the car, the possibility of a breakdown cannot be ruled out. It is necessary to pass every 10,000 - 15,000 mileage Maintenance to troubleshoot the car.
The most common faults:
- Due to low-quality gasoline, problems arise with fuel injection;
- Every 3-5 years, a radiator needs to be replaced due to its increased sensitivity to substances that are on the road in ice in winter
- If during acceleration vibration is felt in the front of the engine (usually after 100 thousand run), then you need to change its rear support
- Both automatic and mechanical box the gears of this model are quite reliable and rarely go out of service, but after 150,000 km of run, the backstage of the manual gearbox lever needs to be repaired or replaced.
- In electrical equipment, the starter or generator sometimes fails.
- Replacement every 70 thousand km rear shock absorbers.
However, in general, this car, does not cause problems for the owners, and its repair is quite "budget".
Changing engine oil and oil filters
Change engine oil And oil filters will have to be every 10-15 thousand kilometers, and in urban conditions with constant traffic jams sometimes you have to change the oil and filter earlier.
Gear oil changes less frequently, somewhere in 50-60 thousand km. However, if you have been on the gas for a long time or towed someone else's car for a long distance, replace transmission oil may need to be earlier.
All oils are filled only with those brands recommended by the manufacturer.
Engine and chassis diagnostics
Engines on this model Hyundai set following volumes: 1.5 l, 1.6 l, 1.8 l, 2.0 l.
The main causes of engine malfunctions of these brands of cars are low-quality gasoline, bad engine oil and high mileage car.
If the following symptoms appear, you need to contact a car service and diagnose the Hyundai Elantra engine:
- Loss of power and unstable engine operation;
- The occurrence of knocking and a sharp popping sound during a "cold" start;
- Increased noise.
It is not worth trying to repair the high-tech motor of this model yourself. In order not to harm your car, it is better to immediately contact a specialized center.
All parts of the chassis of this model and suspension are characterized by a fairly long service life. Careful operation allows you not to change levers and not repair tie rod more than 100,000 km, and stabilizer struts roll stability can "pass" more than 50,000 km without problems.
However, the terrible state Russian roads affects very negatively on the state of the chassis of this Hyundai model. That is why car owners have to change the components of the walker.
It is recommended to carry out diagnostics and repair of a car only in specialized technical centers, since an incompetent replacement of these nodes threatens to get into an accident due to technical Hyundai malfunctions Elantra.
