CEL Code Help. Options

[travisxcore]

I for the life of me can't find out what this CEL code is. First background- Currently my ST204 has a hardly leaky rear main seal or it could have been the PCV Valve cause it had oil in it and after cleaning it out it doesn't seem to be dripping but I haven't really looked into it yet but by checking the dipstick every day. So I'm pulling out of the house yesterday to head to work and the CEL comes on. I go around hoping someone has a code reader for it, which of course no one does so I jump TE1 and E1. Now to the actually important part-

Click for video.

I think its a "No Code" but my buddy up at the shop (old imports aren't his thing...) thinks it could be 22 (Water Temp Sensor). Any guesses?

I haven't cleared the code yet, I'm going to in the morning to see if it comes back or if it was just some freak of nature because this is the first time I've EVER had it come on, shes pretty good to me so far

I got codes 12(1 flash, Pause, 2 flashes) and 22 (2 Flashes, Pause, 2 Flashes)

In my haynes manual it says the following for all celicas except the 2S-E models

Code 12- RPM Signal

Diagnosis=
*No "Ne signal to the ECM within several seconds after the engine is cranked
Or
*No "G" signal to the ECM two times in succesion when the engine speed is between 500 rpm and 4000rpm

Trouble area=
*Distributor Circuit
*Distributor
*Starter signal circuit
*Ignitor Circuit
*Ignitor
*ECM


Code 22- Coolant Temperature Sensor Circuit

Diagnosis=
Open or short in the coolant temperature sensor circuit

Trouble Area=
*Coolant temperature sensor circuit
*Coolant temperature sensor
*ECM




I would check all the wires on/around your distributor and ignitor and clear the code to see if it goes away. You can check the temp sensor with a multimeter or replace it, they are fairly cheap. Hold the temp sensor in a pot of water on the stove with a thermometer to measure temp, then use the multimeter set to resistance(ohms the funny upside down u) and put the leads on the two terminals of the sensor.
Resistance is (roughly)
2k ohms @ 70°F
1k ohms @ 100°F
.7k ohms @ 140°F
.4k ohms @ 175°F
.2k ohms @ 212°F
