The truck shifts very weird and seems to have almost no power. not sure if the two are related but i did manage to pull the codes. the MIL is not on so the normal scan brought up no codes but there were other options on the scanner. When i did the Key on engine off scan it brought up these codes:
-P1705- Trans. Range not indicating park or neutral durring test
(truck was in park position)
-p1218- (cid) high
-p1219- (cid) Low
Then i did the continuous test on it it brought up these codes:
-P0500- Speed Sensor
-p0603- PCM keep alive memory (KAM) error
-p0344- Camshaft position sensor intermittent.
-p0470- Exhaust Pressure sensor.
I have read codes on alot of vehicles but not sure where to start with all of these codes on there at one time. Another thing is that it will not let me erase the codes. For now i plan on going around to all the connectors i can find and spraying them with electronic cleaner and then the di-electric grease. Has anyone ever had a bunch of codes like this? im wondering if i might need a new PCM. Thanks for reading.
the p0500 code is your vss sensor (vehicle speed sensor) which is located on the top of the rear axle, replace that, and if it still shifts hard them your "tone ring" or something like "vehicle speed/abs ring" is bad, i had the same problem. The tone ring is located in the rear axle and you have to pull the axles and diff out, its really not that hard, you just need tq specs and some air tools. I replaced the sensor and nothing, so i got the tone ring and it fixed it. My truck had sit for two years with some water in the axles and it rusted my tone ring. The P/N is E7TZ-4B409-A at the dealership.
The CPS is a $30 part at the dealership, this is an important sensor you do not want to skimp out on the quality, b/c this sensor will leave you stranded. I dont have the part number but its very easy to replace check the 7.3 tech files/ repair help ---> 7.3 Cam sensor replacement procedure
