Hello there Scotty, I have a 2009 Versa Hatchback with the 1.8 L engine and 194,000km on the clock and the Service Engine Soon light has come on with code p1421. For the fun of it I cleared the code a number of times with my code reader but it pops up again in a day or two. I have an idea what is causing the code but I'd like your professional opinion.
Thanks, Wayne

Start with simple things. Change Air filter. Pressure test fuel pump or pressure clean fuel injectors. Pray it’s not bad computer.
