20 Most Recent 2003 Hyundai Elantra GLS Questions & Answers

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.

Look for a hose coming out of your firewall running down to the bottom of the car

Question edited for clarity. Possibly, some do cover things that affect starting, the 'fuel pump relay' for instance. You need to diagnose, not just replace as a guess. Check for codes. A prograde scan tool will diagnose all modules and relays. https://www.autogenius.info/hyundai-elantra-2005-fuse-box-diagram/ ..

Replace the receptacle.

No, it doesn't

Hi more info needed make modle year. do you know if the injectors are pulsing?? You may have fuel in the rail but if the immobiliser system has shut down the injectors it can't start. If they are working then do a compression test and check the timing belt/chain. Regards Jim...

SHOULD BE UP.

It is easier to cool a warm engine that to cool an engine at almost over heat condition. So manufacturers run the fan as soon as the engine gets to operating temperature and that gives the cooling system more control of the heat in the system

No window but some cars have a small plug you pull out to see and some do not general rule of thumb is if it has 100000 change the belt or you can ruin an engine

Have u checked the main fuse in the car? Should b like an 80amper, good luck!

take it to a dealer. it very hard to get them out if they are stuck.you will damage your cly head

disconnect the earth wire from the battery and place a multi meter in the circuit and read the current draw through the current (AMPs) section of the meter. That will tell you what is drawing current and how much.. Things to check include the glove box light is off, boot light is off. the radio amp is off when the ignition is off. When you have done that hook the multimeter across the battery after replacing the earth wire ( red lead to positive and black lead to negative) and start the engine hold RPM at around 1200 and read the voltage in the battery It should be 14.5 volts dc now set the multimeter to read ac and see if you have any voltage there IT should be 0 voltage . That will show that the alternator and rectifier diodes are ok. Check that the drive belt is in good condition and tensioned right.. You say 3 batteries in 13 months . How many have been brand new out of the battery shop type and how many are new to you from some place else. If they have not been new as off the shelf new then have a load test done on the battery as it may have an internal short

I'm thinking Coil pack or cam trigger but let the pro's come in to back me up now.
