I have replaced the hole thing I also replaced the blue and orange wire to pin 85 what next?FROM GOOGLE
"When the P0320 diagnostic trouble code is stored by the Engine Control Module (ECM), it is an indication that there is a malfunction in the ignition/distributor engine speed input circuit."
"P0340 is a diagnostic trouble code (DTC) for "Camshaft Position Sensor Circuit Malfunction". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation."
You really really need to revisit your camshaft position sensor and synchronizer body
Cylinder number one must be at top dead center on COMPRESSION STROKE when the synchronizer is installed with the sensor in the correct position using the alignment tool
When I google "P0340 5.0 explorer"
Just replaced my camshaft position sensor and the synchronizer because it was squealing pretty bad. Got everything lined up properly (I think) and put it back together. Truck runs fine and no more squeal. But now the second or third time I run it, the check engine light comes on. Pulled the...www.explorerforum.com
In the very first post of this thread you said you changed the camshaft position sensor..... I suggest that if you just changed the sensor you need to revisit this, the body of the synchronizer could be the issue, when the bearing wears out the cam sensor will wobble and destroy the sensor on top, a new sensor will only just get destroyed again. Those two codes point directly at an issue with the cam sensor/ synchronizer assembly and/or alternator noise issues (not very common) With your miles I would bet on the cam synchronizer itself is bad, needing the entire assembly replaced.

I only mention because when mine started squealing one day i took and poured a cap of oil in top to lube the bushing and been fine ever since. Note i did not move or replace anything i just got down deep enough to pour oil in the top and as a safety did put it at tdc before removing anything. I also have a new one in the shop waiting for someone to change it but im rebuilding the trans now soooo. Going off what i saw it seemed pretty straight forward just as you said its the same as replacing a distributor pretty much.The synchronizer is a basically a very simple distributor, no sensitive electronics in it, but it installs exactly like a distributor. Anyone who has worked on engines much at all, knows well that it's easy to get the thing installed one tooth off, or 180* off. People familiar with the Explorer 302 know that the synchronize is likely to need replacement when it gets high mileage, the bushings wear out and often squeal before they take out the sensor. We also know the OEM Ford is the only one you should trust, other brands are known to have weak drift pins holding the gear on the shaft.
Bottom line, if it's replaced with a Ford unit, and the proper tool is used to set it, they are very reliable for a long long time. The wiring is old and brittle now, all of them. So more faults will happen due to electrical wire breaks or bad connections. We are guessing here, the cam synch is just a good bet based on the error codes pointing to that circuit.
The tool to install the sensor correctly when at TDC, is very simple and only goes on one way, and at the proper orientation. People have claimed to R&R those and not use a tool, and have the engine run okay or well. To me that's like installing a distributor and not bothering to set the initial timing, doing it by ear etc.
the 94-95 4.0 cam synchros had a glass sight window....never the 5.0Isnt there also a window cut out for the sensor to read that helps you line it up right?
Try a new Knock Sensor, they go bad especially in a corrosive environment, good luck to ya.I have a 2000 explorer 5.0 with 286,000 on it and having serious issues excelerating it seem to be losing power , backfiring until I let off the throttle, I have changed the cam position sensor, throttle sensor, crank sensor don't no what else to try any help would be greatly appreciated
