ecu codes
 

Hi all, quick question for anyone who can help:

A few days ago my driver's side heater hose ripped and started leaking, so I limped it home while stopping every mile or so to top off the coolant. I did not overheat the engine while doing this, as it never ran out of coolant or rose in temperature above normal operating.

I replaced the hose today, and ran it, and it ran fine. However, my check engine light is not permanently illuminated. Before this incident, for the past year and a half, it was intermittent, from my throttle position sensor. When I would step on it hard, the light would go off, and at idle it would come back on.

I grounded the code wire, and read a code for the throttle position sensor, intake air thermosensor being fixed at 68 degrees, and for the crankle angle position sensor ne. What would cause this light to permanently come on now? I have read that the crank angle sensor rarely goes bad, so I am hesitant to just throw parts at it by replacing it. On top of that, it runs and idles fine. Anyone have any input on this?
