Hyundai Elantra Check Engine Light Troubleshooting

Asked by Hyundai2017Elantra Feb 01, 2023 at 03:45 PM about the 2017 Hyundai Elantra SE FWD

Question type: Maintenance & Repair

The original code was the MAP sensor, with a secondary of the cam Bank 1
sensor 2. After changing the MAP, the light came back on with Cam 1/2 as
the primary code, with a secondary of Crankshaft sensor. After changing
Cam, the code read primary Crank, secondary VVT exhaust solenoid. After
changing both, the codes started over with the Cam sensor, with a
secondary code of crank sensor. Went to a mechanic for a second opinion,
mechanic changed VVT solenoid and cam sensor, all plugs and coils, and
performed an oil change. When i received the vehicle back from the
mechanic the check engine light was still on and he is stating the timing
chain as the issue. when I received the vehicle back, there was also a new
code for open circuits 3,6 I did discover the two PDM relays had been
removed and not replaced and a couple blown fuses which i corrected. The
vehicle is still throwing P0017 and P0014. The vehicle has no drivability
issues, excellent gas mileage, no rough idle, no clanking, so it is difficult to
believe the timing chain would be the issue.

Ah, the wonderful world of Hyundai. It's past its b2b warranty and mechanics tend to not want to work on them. You should rely only on dealer mechanics for these cars. Do that and you might get another five years out of that POS.
