Question about 1997 Honda Civic

1 Answer

I have a Honda Civic 1997 Two door Manual and my check engine light is on. I went to have the codes checked out and was given two; PO505 and PO420. I think it's Idle Control System Malfunction and Caflis Efficency below Thresh Hold Bank 1. Could you possibly elaborate or give me the run down about costs?

Fix the idle control first, it may be causing the 2nd error code.

I change my transmission in 1997 honda civic freio I change the cvt to a manual transmission andengine check light stay on what could cause that to happen


Check engine lights report faults in engine AND gear box(auto). If you have changed from an auto to manual gear box then the sensor system for the gearbox is recording a massive fault with the gearbox that you have to check out. Talk wit an accredited auto electrician as to how to neutralise the system so that the light only checks out the engine.

Check engine light on just after 100K


a check engine light has nothing to do with oil, it is a warning that some part of the engine or emission control system electronic control systems has developed a fault, have the system tested to determine what that fault is, there will be a fault code stored in the powertrain control modules memory

Honda civic 2000 problem code PO420


P0420: Calayst system efficiency below threshold (Bank no. 1)
You can clear the code by turning your engine off, locating fuse number 12 in your under hood fuse box (backup, radio 7.5A) and pulling that fuse for about 10 seconds. If the code comes back, it was not a glitch and I would have the code checked out (has to do with you catalytic converter, I believe).
Hope this helps you.

Honda civic code PO420


Code P0420 Catalyst System Efficiency Below Threshold (Bank #1) Can't really say if driving it that long would cause damage.
