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.

since you jumped the gun and replaced the sensor, it would be wise to examine all the wring for chafing anywhere.
