Do I have 3 codes on my NDA CRV P0420, P0845, P1456 since 2002? 3

The P0420 is designed for catalytic converters that have reduced their ability to handle emitted gases. The code states that the catalyst in the converter was used to convert hazardous gases to such an extent that the converter's ability to process or convert flow gases is less than 50% of its ■■■■ capacity.

This does not mean that the converter is bad. That is, ineffective. The car won't stop or cause driving problems, but it won't pass the pollution test unless you replace the converter.

The P0845 is for automatic pressure shifting in third gear. This code indicates that the switch is not reading pressure, indicating that the third gear is engaged. Without the addition of third gear, the converter clutch does not lock. This problem is usually caused by bad software.

P1456 is a well-known code for loose fuel caps for the evaporation system. In 2002, the emission control system detected a small leak in the vapor emission system and assigned this code. Most people think that this is a loose fuel cap, which is not uncommon. The code can also mean that many other things can be leaked. The advice is to tighten the fuel cap and see if the code disappears after about a week.

For example, who helps?
