Question 1

1answer

2003 Hyundai Elantra GL. I have a P1140 code, I changed the MAF sensor twice it's not the problem, engine light keeps coming on. Any help would be appreciated.

The P1140 code in a Hyundai refers to the Intake Valve Timing Control Solenoid Valve. This valve is part of the Variable Valve Timing (VVT) system and is responsible for controlling the timing of the intake valves to optimize engine performance.
If you've already replaced the Mass Air Flow (MAF) sensor and the issue persists, here are some additional steps you can take to address the P1140 code:
1. **Inspect the Intake Valve Timing Control Solenoid Valve:**
Check the wiring and connectors associated with the Intake Valve Timing Control Solenoid Valve. Ensure there are no loose or damaged connections. If the wiring appears damaged or there's a poor connection, repair or replace as needed.
2. **Check Oil Levels and Quality:**
The VVT system relies on proper oil flow and pressure. Ensure that the engine oil level is correct and that you are using the recommended oil viscosity. Dirty or low-quality oil can affect the proper functioning of the system.
3. **Test the Intake Valve Timing Control Solenoid Valve:**
You may need to test the solenoid valve to ensure it is functioning correctly. This involves using a multimeter to measure resistance and checking for proper operation. Refer to the vehicle's service manual for specific testing procedures.
4. **Verify Timing Chain/Belt:**
Issues with the timing chain or belt can affect the VVT system. Check the condition and tension of the timing chain or belt. If it's worn, stretched, or damaged, it may need replacement.
5. **Scan for Additional Codes:**
Perform a comprehensive OBD-II scan to check for any additional trouble codes. Sometimes, addressing related codes can help in diagnosing the root cause of the issue.
6. **Professional Diagnosis:**
If you're unable to identify and resolve the issue through the above steps, consider seeking professional help. A qualified mechanic or Hyundai dealership may have specialized diagnostic tools and expertise to pinpoint the problem.
Remember, the VVT system is a complex part of the engine, and addressing issues with it may require a systematic diagnostic approach. If you're not comfortable performing these steps or if the problem persists, seeking professional assistance is advisable. They can perform more in-depth diagnostics and provide a precise solution based on the specific conditions of your Hyundai Elantra GL.

I have an 2008 Hyundai elantra and get code 700& 760 what that mean?

Code 700 is a generic code that means a problem has occured with the transmission control module, and code 760 is for a shift solenoid failure.
The shop would use a repair manual to test the circuit for the shift solenoid. If the solenoid is faulty, it would need to be replaced and the module reset.

SOURCE: How to replace 2004 Hyundai Elantra starter

First, disconnect the battery. Then the only part that needs to be removed to access the starter is the rubber air plenum boot between the throttle body and the air filter housing. This allows enough room to get an arm in there to access the 14mm bolts that attach the starter to the transmission. After removing the bolts, the starter can be removed from underneath the car. lower it down as much as possible, and unbolt the power cable. You may have to twist and turn it a bit to get around the support between the engine block and intake manifold, but it will come out.
