When does a Hyundai Sonata starter go bad?
If there is power, the starter is bad. If it does not have power, then there is a break or open in the wire from the relay to the solenoid. If there was no power at the second terminal at the relay, check the neutral safety switch on the transmission.
How does the starter relay work on a Hyundai Sonata?
In order to activate the relay the power goes from the accessory fuse to the ignition switch and then to the security alarm device. From the security alarm it must go to the neutral safety switch which prevents the car from starting in any gear except park or neutral. From this point it passes to the starter relay and to ground.
What happens when you shift to a lower gear in a Hyundai?
Moreover, it’s been reported that after shifting to a lower gear, the driver is unable to shift to another gear. On such occasions, drivers have temporarily resolved the problem by turning the engine off then restarting it. However, once the vehicle restarts and is running, the problem usually recurs.
What should the voltmeter be on a Hyundai Sonata?
Set the voltmeter to 20 volts dc. Check the battery—it should have 12.5 volts or more. If it has less than 12.5 volts, the battery or charging system is suspect. It is possible for a battery to show 12.5 or better on voltage and a bad cell, which would kill the amperage output.
Why does my Hyundai Sonata not accelerate when I push the gas?
If your Hyundai Sonata won’t accelerate, that is a serious cause for concern. There are a lot of different reasons that can cause this. Diagnosing the issue can be narrowed down by whether the engine is still revving when you push the gas or not. There is a section for each scenario with likely causes for each.
Why is the timing chain on my Hyundai Sonata not working?
The timing chain (or belt) is responsible for keeping the upper valve train synced with the crankshaft. This is vital for spark timing. If the timing is off a little and the engine still runs, the timing belt may have skipped. If it has jumped too much the Sonata may not even fire.
If there is power, the starter is bad. If it does not have power, then there is a break or open in the wire from the relay to the solenoid. If there was no power at the second terminal at the relay, check the neutral safety switch on the transmission.
How to troubleshoot the ignition system in a Hyundai Sonata?
Follow Steps 2 and 3 if the Sonata has a 2.7 or 3.5L engine, Steps 4 and 5 for a 2.4L engine. Probe terminals 1-4, 2-4 and 3-4 with an ohmmeter. The primary resistance on each should be within 10 percent of 0.74 kohms for a 2.7L or 3.5L engine.
Do you need spark test on Hyundai Sonata?
If you need to check your Hyundai Sonata’s ignition system for trouble, check to see if it’s a distributor-based system or not. A distributor ignition system needs a spark test and the ignition coils checked. On a distributorless system, you use a different method to check the coils only. Connect a spark tester to a disconnected spark plug wire.
