I have a 2001 nissan maxima my obd2 scanner was throwing a p1335 code. The car started fine ran good but it had a 0420 code for years now. Bad cat. I ordered the 2 crankshaft position sensors and put them in. It started hard now and still is throwing the p1335 code. The 0420 stays off now. I tried the old cps and same thing. Whats changed? I'm stumped. Once the car starts it runs fine but the hard start keeps throwing the code back on.
