Starting and driving issues

In most cases with the po420 code the catalytic convert needs to be replaced to fix the problem. If the P0420 code is combined with other codes, try fixing the other codes first.

Isn't the cam and crank sensor the same thing? I have replaced the one on the right side of block near the transmission was a little hard to get to and get out, when I got the part I asked for a crankshaft position sensor. Is the camshaft sensor in another location, thanks for your help

Went and found it at my break, I will be picking up the part once I'm off work thanks for the advice

I have fixed my stalling issue it was the camshaft sensor, thank you for the help, I am still having starting issues, still cranks a few times to get it started. Starts fine in the morning. Now if I drive and park for a few min go to start it cranks a few times and then will finally start, I have code po700 that has been coming on, and every once in awhile po420, I rest the codes and the po420 goes away and then once I drive about 50 miles on the freeway the po700 come on, I am not having shift issues. About 3 days ago the trans temp mil came on and then went off after a few min and has not came back on since, truck has about 250k and all maintenance has been done since I have had it. Any thought will help thanks

If it is still doing it....unplug your battery and tie the 2 cables together for 30seconds...it reset the brain to read that specific cam sensor
