What do codes p0335 and p0341 mean on 1996 Cavalier?

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 ...

EOBD Codes:

• P0341 - Cam Position Sensor signal error- check wiring.connector,bolted securely. Or sensor itself damaged.
• P0571 - brake switch wiring or ECM problem
• P0609 - VSS-vehicle speed sensor output -ECM problem if wiring is OK.

This P0341 code basically means that the powertrain control module (PCM) detected a problem with the camshaft signal. The camshaft position sensor (CPS) sends a specific signal to the PCM for Top Dead Center on the compression stroke as well as signals indicating the position of the cam sensor. This is accomplished through a reluctor wheel attached to the camshaft that passes by the cam sensor. Any time that the signal to the PCM is inconsistent with what the signal should be, this code is set. NOTE: this code can also be set by extended cranking periods.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook Symptoms The car will likely run with this code set, as it is often intermittent and also because the PCM can often operate the vehicle in "limp-in/limp-home" mode even with a cam sensor signal problem. There may be no noticeable symptoms other than:

• Poor fuel economy (if engine runs)
• Possible no start condition

Causes A code P0341 may mean that one or more of the following has happened:

• Cam sensor wiring routed too close to spark plug wiring (causing interference)
• Poor wiring connection at cam sensor
• Poor wiring connection at PCM
• Bad cam sensor
• Damaged reluctor wheel

Possible Solutions Often relacing the sensor fixes this code, but not necessarily. Therefore it's important to check the following:

• Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.)
• Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing
• Visually inspect the cam sensor for damage
• Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage
• If reluctor isn't visible from outside the engine, visual test can only be done by removing cam shaft or intake manifold (depending on engine design)
• If all checks out okay, then replace the sensor.

a p0341 code mean cam reference performance, really it means you have a secondary ignition problem,,,,like a bad ignition module
a bad crank sensor
a high resistance spark plugs,do not use bosch platinum plugs in these cars
high resistance spark plug wires,,,i work at the dealer and the first thing we do is replace the spark plugs and wires if that dont work we replace the crank sensor,if thatdont work we reaplce the ignition mondule,and by then your fixed and you started with the cheapest items first,,,i would try plugs and wires and a crank sensor,,,,wires $50 plugs $14 crank sensor $37

In the kit there are two sensor that look identical. The one for the crankshaft has a white paint mark on it near the bolt hole. Make sure that it is in the right location.
