Hello I have a 95 honda accord and I got these codes but not sure what I have to do to fix them, if anyone can help that would be great. I have engine code 17, 12, and 59. And abs code 14. Thank you for any help provided.

 

I looked at your other post to see that you have a 4-cyl VTEC with a 5-speed manual transmission. That information is always helpful in the post.

My list shows 17 is for the VSS (on a manual-trans) so check the wiring on that before you just buy a new sensor.

Code 12 is for the EGR valve. Check that, but before going too far check whether the EGR passageways need to be cleaned out. With Hondas, it's common for the EGR valve to be OK but the passageways through the intake manifold are plugged up with carbon.

My list doesn't have a code 59.

ABS code 1-4 is for the pressure switch. Look for wiring problems on that, and then I hope someone chimes in who has more information about that.

 

The 95 wasn't great at determining EGR flow. Cleaning the EGR ports is a good idea regardless, but will not likely eliminate a code 12.

Follow the vacuum hose from the EGR valve to the control/vacuum solenoids that sit on the driver's side of the engine bay. Check the vacuum hose along the way for cracks/dry rotting, especially under the control valves.

I don't see a code 59. I'd suggest resetting the ECU by pulling the 7.5 amp backup/radio fuse in the engine bay fuse box for a minute. Drive until the CEL returns and recheck the codes.
