good evening my name is ***** ***** I will assist

first, I need the code number. a lot of the time, cam sensor codes indicate a timing correlation issue between the crank and cam sensor. I would have the valve timing checked to verify the engine is in correct time. it would also explain why it starts hard and stalls.

I would start with a timing check

  1. CMPS #1

General Description

The Camshaft Position Sensor (CMPS) is a sensor that detects the compression TDC of the NO. 1 cylinder. The CMPS consists of a hall type sensor and a target on the end of the intake camshaft. When the target triggers the sensor, the sensor voltage is 5V. If not, the sensor voltage is 0V. These CMPS signal is sent to the PCM/ECM and the PCM/ECM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.

DTC Description

The PCM/ECM monitors the inlet camshaft sensor signal transition position which must change only once per crankshaft revolution. If no camshaft signal is detected while crankshaft signal is detected, the PCM/ECM sets DTC P0340.

Hello. Another cause could be a misaligned crankshaft and camshaft. This could be caused by a stretched timing chain, or something as simple as low oil. Check the oil level, and ensure that you are using a factory Hyundai oil filter.

I have 40000 miles would that still be the timing chain
Hyundai Mechanic: Andrew Martin,

Unlikely, more likely that it is an oil issue or an issue with the oil control valves. Do you use hyundai oil filters or get the oil changed at the dealership? Also, just so you know, your car is still under 5 year 60,000 mile warranty, so any issue you are having you can bring it to the dealership and it is completely covered by Hyundai.

Customer reply replied 1 year ago
I cleared the codes the check engine light is out but still won't idle it started easier but still problems starting
Hyundai Mechanic: Andrew Martin,

How do you know the timing is on? Did you remove the covers and check the marks? Also, you should not use Fram filters, they do not have flow specifications that are up to Hyundai standards. If the P0340 is the only code there not sure what else it could be. If it is having problems starting its more likely that the crankshaft sensor is the issue.
