Cmp please help

I have been searching this site and forums for days now, cannot seem to find the answer I need. My engine light came on, had it tested, came up as the camshaft position sensor. I tested the wiring, it's all good, so I replaced the sensor. Based on what I'm seeing I should notice somthing wrong. I HAVE NO SYMPTOMS. No stalling, no limp mode, no starting issues, no loss of power. Nothing. What do I do next? I do not have the money to take it to a mechanic. TIA!

2004 civic si 2.0L

edit** engine light is still on, yes I reset it, it came back.

Post your actual "P" code.


What's the definition of code P0341?

Which cam position sensor did you replace?
Exhaust cam sensor? Intake cam sensor? Did you replace the wrong sensor?


Where did your new sensor come from?
Dangerzone? Honda dealer?


Could the plugs for intake cam sensor and exhaust cam sensor have been swapped?

With engine running.....Measure sensor wiring for excessive voltage on the ground wire
If higher than 0.20 volts:
Check that the ground wires under the fuel injector rail are clean and tight
Check, disassemble and clean corrosion from the terminals and bolts for the ground cable connections from battery to frame
Same for ground cable from frame to transmission
Same for ground cable from body to engine mount (passengers side)Pull valve cover,


Really far out thoughts:
inspect trigger wheel (reluctor) for the sensor in question: Does it have missing or damaged teeth? Is it loose on the camshaft?
Inspect sensor end for physical damage....excessive cam end play or 'walk'? (not likely)
