Need help with codes P0105, P0341, P1519
My Check Engine Light is on. The CEL as been intermittent -- days at a time on or off for many weeks, but now seems to be on all the time. However, I don't notice any particular problems with engine performance.
If needed, here are the descriptions of the codes:
P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
P0341 Camshaft Position Sensor Circuit Range/Performance
P1519 Idle Air Control Valve Circuit Failure
I think usually these are related to problems with vacuum hose leaks, the camshaft position sensor itself, the camshaft adjuster magnet, and/or with oil fouling up sensor connections. I cleaned up some oil-fouled sensor connections under the front gray engine cover (some oil apparently leaking from the camshaft adjuster magnet, but not much), then erased the codes, and the codes stayed off for a week then came back on. Vacuum hoses under the gray cover seem okay.
Does anyone have any definite parts to look at or test, other than starting to replace parts?
