99 Neon sohc keeps wipping the cam and crank sensors

do have to? there is never any answer to that, nu-diagosed.

no engine told. at all. just 4 banger
no VIN told and 8th digit is engine code.! post VIN .
crank sensor can be in 3+ places, front crank ,mid crank and rear.
yes some car with crank sensor behind fly wheel the tone slots are cut into the flywheel or the (flex plate) so yah tricky on some engines. (just so you know ropes)

if you google correct engine name + crank shaft.

you will see the tone wheel on the crank and bingo location
or read the service manual to learn this fast.

I4 means zero to me
see why?? the wiki shows this generation used all 6 engines
2012 up.

Petrol:
2.0 L 4J11 I4
2.4 L 4B12 I4[29]
2.4 L 4J12 I4[30]
3.0 L 6B31 V6[31]<<< NO
Petrol PHEV:
2.0 L 4B11 I4
2.4 L 4B12 I4
Diesel:
2.3 L 4N14 I4 turbo[32]

if the engine has CAM belt it snapped, and both sensors fail but both sensor are good, and fails compression tests or worse
head poppet valves bent./
my guess someone (kids) put you up to this guess.
or did not scan he PCM
or did not inspect that cam belt?

I flat refuse to do all of those with belt/chain, told.NO!

replace cam bearings it should be a trust bearing in that position is worn and faulty

Have you looked at the ignition module, or and ignition switch. Not the key switch} ignition switch.

are you using a factory sensor?i would check the end play on the crank shaft they had a problem with the thrust bearings

If you are 180 deg off then you will have to remove the timing belt...turn the cam shaft 180 degrees and then re-install the timing belt

Hi, my name is John I will do my best to assist you.

To Remove

1. Disconnect the negative battery cable.
2. Disconnect the filtered air tube from the throttle body and air cleaner housing.
3. For SOHC engines, remove the air cleaner inlet tube.
4. For SOHC engines, detach the electrical connectors from the engine coolant sensor and the camshaft position sensor.
5. For DOHC engines, unplug the electrical connector from the camshaft position sensor.
6. For SOHC engines, remove the brake booster hose and the electrical connectors form the holders on the end of the cylinder head cover.
7. Unfasten the camshaft position sensor mounting screws, then remove the sensor.
8. Loosen the screw/bolt attaching the target magnet to the rear of the camshaft.

To Install: NOTE: The target magnet has 2 locating dowels which fit into the machined locating holes in the end of the camshaft.

1. Install the target magnet in the end of the camshaft. Tighten the retainer to 30 inch lbs. (3.4 Nm).
2. Install the camshaft position sensor. Tighten the sensor mounting screws to 80 inch lbs. (9 Nm).
3. For SOHC engines, place the brake booster hose and the electrical harness in the holders on the end of the valve cover.
4. Attach the electrical connector(s) to the camshaft position sensor and coolant temperature sensor (if necessary).
5. Install the air cleaner inlet tube and the filtered air tube.
6. Connect the negative battery cable.

The camshaft position sensor is mounted to the rear of the cylinder head - SOHC engine shown



Location of the camshaft position sensor - DOHC engine shown



Unfasten the retaining bolt, then remove the target magnet from the rear of the camshaft - SOHC shown, DOHC similar



The target magnet has 2 locating dowels for proper alignment during installation

Spray wd40 down the air intake while cranking the car if it fires off and tries to start
it is most likely at least partially the fuel - pump and or filter [s]

How old is the battery? Clean the connections, charge the battery. Try starting it. Get the battery tested at Autozone or some place like that.
