Crankshaft position sensor/clogged catalytic system?

Hello, are you still getting the P0430 code as well? The P0335 code is a circuit code, meaning the sensor may not be receiving the correct or no feed voltage, has a bad ground to the sensor, or the signal wire for the sensor is not complete all the way to the engine computer. Do you own a scan tool? It may be both. the Catalytic Converter for Bank 2 may be failing and you may have a wiring issue to the sensor. With high mileage vehicles they tend to end up with multiple issues sometimes because vehicles are not designed to last unfortunately. If you have a scan tool and or a basic multimeter we can check that the crank sensor is getting power and ground to operate. I will pull up the wiring diagrams to show which wires should have 12volts on one and ground on another with the Key On.
the P0335 sets when the engine computer is seeing a camshaft signal but no crankshaft signal, so I dont think youre getting bad sensors, I believe you have a wiring issue to it. Will post further information.

Here is how to test for Power and Ground at the Crank Position sensor harness plug. You can check this with the sensor unplugged. Just dont push the meter leads into the wiring harness plug for the crank sensor, just touch the female pins with the leads while the key is On. The 1st diagram shows the wire colors. This is a 12volt sensor so checking across pins 1 and 2 will verify 12volts and Ground at the same time. Let us know if you have any questions.
As for the P0430, Catalytic Converter failures are due to cylinder misfires because of unburned fuel exiting the cylinders and getting down to the Converter which in turn over heats it and they melt down and restrict the exhaust. This causes a huge lack of power, hesitation, stalling, etc. Im not sure how the dealership missed it. Unless the code was cleared at that point. It may take a few drive cycles before the code will set again if erased. But we will deal with the P0430 after we get your crank sensor figured out.
To check the Signal wire (pin 3) going back to the engine computer, touch the red meter lead to pin 3 (blue wire) and the black meter lead to pin 2 (brown wire), and the meter should read 5volts. Honda uses what is known as a bias voltage on the signal wire to check circuit integrity. This way you dont need to go all the way to the engine computer to check the signal wire from the crank sensor plug.

Thanks for your quick response. I will let you know later. Right now, my car is driving better, and I don't have any engine lights on.

Okay, that is a good sign. Make sure that the pins in the connector for the crank sensor are tight and there is a good connection. But aftermarket sensors can definitely cause all kinds of problems. Good idea to go with an OEM.
