All the misfire codes have dissappeared and now theres only P0 320. Is it normal for these to go? my Truck is completley dead except it tends to catch then stall within a mater of seconds. also just trying to get to the sensor seems to be a pain being baried under the firewall. whats the best approch. also would this cause the engine to suddenly die with no apperent cause , and no previous problems?

 

It is possible for these to go out suddenly on any vehicle. It was probably the cause of your original misfire codes. I have always found it easiest to pull my air cleaner off, put a towel over the throttle body, lay a piece of plywood across the top of the engine, and then lay on the plywood while reaching to remove the crankshaft position sensor. Some people go at these from below as it is easiest for them.

You can do a search in the 2nd gen forum on the crankshaft position sensor and find a lot of information. Basically, the CPS is a sensor that points down into your bell housing and using the Hall effect reads the evenly spaced openings in the flexplate. The sensor sends a signal to the computer which tells the ignition to fire. The sensor points basically straight down through the bell housing and there is a rubber grommet that seals water and junk from getting into the bell housing area.The CPS is attached to a L shaped bracket where the CPS is in the bottom of the L and two bolts go through the top of the L and bolt into the rear of the head.

When you reconnect the electrical connection, use some di-electric grease on the connection so moisture doesn't get into the connection and cause future problems.

Hope this helps.

 

Thxs much for the info. best regards
