On my 97 Sunfire the check engine light was staying on all the time. My scanner gave me a P0342 code. I cleaned the connection to the cam position sensor and coated the wires with insulating grease. The check engine light went out but now comes on again after 10 to 15 minutes of driving. When I shut of the engine and restart it 3 times the light goes out on the 3rd start but comes on again after a few miles. Again 3 starts and the light goes out and so on....Do I need a new sensor or could it be wiring or something else?

The codes signify issue with the same component.

P0341 What the P0341 code means. P0341 is an OBD-II generic code that says the engine control module (ECM) detected the engine camshaft position sensor circuit is not within specifications. The sensor pulses do not correlate to the pulses of the crankshaft sensor.

P0342 Code: Camshaft Position Sensor "A" Circuit Low

https://www.carparts.com > blog > p0342-code-camshaf...
Dec 15, 2021 - P0342 is a diagnostic trouble code (DTC) that stands for "Camshaft Position Sensor 'A' Circuit Low." It basically means that your PCM is not ...

It wouldn't be P00342 - P0342 is correct . Did you check the code on youtube . for repair video ?

Question is does the O2 sensor wiring integrate with the cam position sensor and cause this code? ????? No it doesn't .
Circuit Description
The camshaft position (CMP) sensor works in conjunction with a 1 X reluctor wheel on the camshaft. The powertrain control module (PCM) provides a 12 volt reference to the CMP sensor as well as a low reference and a signal circuit.
As the camshaft rotates, the reluctor wheel interrupts a magnetic field produced by a magnet within the sensor. The sensors internal circuitry detects this and produces a signal which the PCM reads.
The CMP sensor 1 X signal is used by the PCM to determine if the cylinder at top dead center (TDC) is on the firing stroke or the exhaust stroke. The PCM can determine TDC for all cylinders by using the CKP sensor 24 X signal alone. The engine will start without a CMP signal as long as the PCM receives the CKP sensor 24 X signal. A slightly longer cranking time may be a symptom of this condition. The system attempts synchronization and looks for an increase in engine speed indicating that the engine started. If the PCM does not detect an increase in engine speed, the PCM assumes that the PCM incorrectly synchronized to the exhaust stroke and re-syncs to the opposite cam position. If the PCM detects that a CMP signal is constantly low, DTC P0342 sets.

Diagnostic Aids
The following conditions may cause this DTC to set:
• Camshaft reluctor ring damage
• The sensor coming in contact with the reluctor ring
• Foreign material passing between the sensor and the reluctor ring
• Excessive camshaft end-play
• Wiring routed too close to secondary ignition components

code p0342 refers to cam shaft position (CMP) sensor A bank 1 --low input===causes--wiring short to ground---CMP sensor---ECM
Check for wiring shorting out on the engine /body, replace the cam sensor on bank 1

Clean the throttle position sensor.

This is a camshaft position sensor this sensor may be going bad they are usually located on the front of the motor up hi where the camshaft is.

It's quite likely that you have an open circuit between the fuel sender harness and the chassis ground. This would cause this combination of DTC's as the ground is a common point for both of these components.

With the key on, engine off, disconnect the cam position sensor wire (3 pin connector) and check the ground for resistance between pin 3 and a chassis ground. You should have less than 1 ohm of resistance. If not then a ground issue is your problem, either obtain a schematic from www.hmaservice.com for your vehicle and check the wire for resistance at each connector from the CMP (cam position sensor) to the ground, or take your vehicle to a local Hyundai dealer who will have the resources to do so correctly in the shortest amount of time.

Cam position sensors go bad, but very infrequently. We see many more Crank position sensors (people confuse the two quite frequently) go bad. In your case, the cam position sensor would be located on top of the cylinder head, not in the engine block. It's located between the valve cover (the very top of the engine, the oil cap is on it) and the coil pack (the thing on the right with the spark plug wires). The connecter between them is what you need to check. Any digital voltage and ohm meter (DVOM) will due. Pin 1 should be 12 volts DC, pin 2 should be 5 volts DC, and I mentioned how to check the ground.

If you get stuck, take it to a dealer. Pin 2 on this connecter goes directly to the PCM (Powertrain Control Module) and you don't want to cook that by shorting it to 12 volts.

Good luck!

Good luck!

the code for camshaft sensor is--p0341 and p0342, po341 is camshaft range or performance problem. p0342 is camshaft curcuit , low input. hope this helps carl.

could be the timing chain. Was it a pop or more like a ping . A ping could indicate a timing chain problem. The tensioner might have gone bad.
its not hard to replace for an experienced mechanic

The computer will have to be scanned for codes, then remove the light with the tool ....you can buy a scanner at Cragens

I had to rebuild my engine at 97000 miles cuz of low engine oil pressure and bad berrings
