yo,
Thanks for the reference bummer!
Yo MG!
Let me just address the Codes Overview for now since I am using a secure PC station here and can't do much due to ... ya know?
Ask if you need to know where components mentioned are located; what they look like, etc..or go to my site and select appropriate sections such as Emission For EGR (Exhaust Gas Recirculation)..etc.
21 ECT out of Self-Test range MAP/BARO out of Self-Test range. ECT is bad,
engine not warmed up , bad thermostat, low coolant
DTC 31 "... This code could be caused by several different factors. If the pintle position sensor (Ford calls it the EVP sensor) is shorted or open, you could have a code set. If the EGR valve becomes carboned up and does not seat fully, the EVP sensor gives a high reading and a code is set. If the diaphragm of the EGR valve is bad, then it, too, is flagged..."

Bad EVP sensor, no exhaust backpressure (really doesn't really cause problems) or inopperative EGR
DTC 32/326 typically means that the EGR valve is not fully seated. This can be due to a bad EGR valve, vacuum trapped in the EGR hose, a clogged EVR filter, or a bad EVR solenoid. It is also important to note that if you have an exhaust ventilation system hooked up, that this can also cause an inaccurate reading. Try disconnecting the system and retesting..."

114 (O,R) IAT sensor out of range
DTC 18 IDM circuit failure or SPOUT circuit grounded; "...The computer sends out a timing advance correction to the ICM over the SPOUT wire and then looks for the change on the IDM wire. You might check the ECT or the IAT sensor for your problem. Also check the SPOUT/IDM wire going to ground..." Bad TFI, bad mag pickup,
DTC 51 - ECT sensor signal is greater than the Self-Test maximum of 4.6 volts...Bad ECT, sticking thermostat, low coolant, clogged convertor
DTC 14 & 18; Profile Ignition Pickup (PIP) & Troubleshooting; "...The top three leads (for PIP signal) can lose continuity with the back plate (ground) on the module when the unit is hot. You should consider a remote mounted TFI. If your TFI is failing from heat, it can give off computer codes 14 (PIP) and 18 (SPOUT). stalling/dieing or sputtering when hot but runs when it cools off. This can be caused by a faulty TFI and the biggest culprits are heat. Another culprit can be a wire grounding out. Problematic TFI's can give off codes 14 (PIP) and 18 (SPOUT)..." TFI module most likely, but mag pickup could be bad
