Before I installed my TF top end kit I had no codes. After the install i'm getting codes 22,31,51,53 and 54. I know what the codes are, my problem is that my ECT,MAP,TPS,ACT and EGR were all bought new within the past 2 months! I looked at a wiring diagram and all these sensors seem to share a red/grey wire. Does anybody think that the wire i'm refering to got cut or damaged? It's strange how some sensors are reading too high and others are reading too low! Plus, I doubt any of these sensors could be bad after only being 2 months old! Could my computer be shot? I disconnected the negative cable before the h/c/i install. Any help would be greatly appreciated!

did you re-attach the braided cable on the back of the motor?

The first thing I thought of was the ground also. I just double checked it and it good.

What wires did you double check?


That braided silver cable usually ALWAYS break from your old heads, during the HCI and the orange ground wire as well.


Another commonality is to pull the salt and pepper connectors, and have one of the wires come loose from the plug or not be snug fit.



That braided wire, should be grounded to the firewall and top tranny bolt or the back of your new head. along with the orange wire with it on the firewall.

AND THIS



Always start by checking the basics: computer diagnostic codes, vacuum leaks, fuel pressure, Cap & Rotor, Plug wires & spark plugs.
Disconnect the negative battery cable! To open the connectors squeeze the four side clips and pull apart. Do not pry the clips apart as with other connectors. Inside you will find ten male and female terminals.







First use a small pick to slightly squeeze the female terminals closed.











Then spread the male terminals open just slightly. This will ensure a complete electrical contact.










Before reassembly take some spray electrical contact cleaner and clean the male and female connectors. Then fill the female terminals with dielectric grease to prevent corrosion.










This problem is not isolated to the salt and pepper 10-pin connectors. The EGR sensor has a history of this problem, and many other Ford connectors. This is a regular maintenance repair you should plan on doing to your aging high mileage Ford.

I only checked the orange wire. I'll check the braided one now. I'll also pull apart the salt and pepper connectors and check them. Thanks for everyones help thus far!

in the connector you can install dialectic grease after repair if it is prob to help aid in conectivity
