The check engine light came on and I put a code reader on and this is the code it gave me P0320 plus the tachometer isn't working now what. Do I do

Hi Chris O have the exact problem. Mine is a 2004 Hyundai SanteFe. H
What did you do to fix -
Just ran into this problem today on a 2005Sante Fe 3.5 V6 with 108k miles. Cranks forever but will not start. Code scan showed P0320.
Starting fluid (ether) did not help when I thought the problem might be a bad fuel pump but I did hear/feel an occasional pulse as a cylinder fired. I held the throttle to the floor thinking the engine might be flooded and it did eventually start but speed came up slowly and "idle" was about 2000 RPM. Tachometer operation was erratic and sometimes dropped to 0 at "idle."
When I cleared the P0320 as the engine "idled" it quit instantly and I had to repeat the "foot to the floor" exercise to get it started again.
I'll replace the ignition malfunction monitor tomorrow and see it the starting/running problem is fixed. -
Have a 2003 Hyundai xg350L and the car starts fine every time. Just replaced the battery but I'm getting the p0320 code ignition/distributor engine speed input circuit and check engine light comes on after the car is running. I have an OBD2 reader and have erased the fault a couple of times but it keeps coming back on. What's the problem here? Also, the crankshaft sensor was replaced in 2015.

The most common cause for the P0320 on your 2003 XG350 is the "Ignition Failure Sensor". The sensor is on upper left rear of engine.
