I've got the manual for the later OBD II system ('96 and later), not the OBD I Trionic ('93-95). Some of the codes are the same.
I've got no listing for P1322. Engine speed should show up as the crankcase position sensor signal, as that is where the ECU gets engine speed. The sypmtom would be the engine failing to start or misfiring. This can be caused by the perforated ring on the camshaft being damaged by work, or a bad sensor. To check the sensor unplug the three pin connector and measure the resistance across pins 1 and 2 - it should be 540 +/- 55 ohms. Pins 1 to 3 should be an open circuit. If the sensor is OK, make sure that pins 2 and 3 are connected to ground. If that doesn't work, make sure pin 1 is connected to the Trionic box (should be pin 41, but this is a NEWER book).
P0120 is the Throttle position sensor. P0120 is the 'all embracing' fault. The symptoms would be Check Engine light ON, high idle speed, and the A/C compressor won't work. Turn the ignition to On then back to OFF. Unplug the throttle position sensor's 3 pin connector. Pin 1 to ground should be about 5 volts, and from the battery positive to pin 2 should be about 12 volts. If not, find the wiring problem. With the sensor connected to the EDU and the car ON, the voltage should swing between 0.5 volts (no foot on pedal) to 4.5 Volts (floored pedal). Otherwise, a bad sensor.
P0135 is a problem with the heater on the front O2 sensor. The symptom would be the Check Engine light on, and little else. If you didn't get a P0141 (rear sensor) ALSO, then disconnect the FRONT sensor's connector (4 pins). Connect a test light (12 volt light) between pin 1 and ground - it should light. Move the light to pin 2 and the positive lead of the battery - it should light. If not, fix the wiring.
This is kind of an odd set of faults. What are the symptoms - why did you get the codes read? Why didn't the mechanic follow the test procedures?
For a random collection of codes like this, I would clear them out and see if they return. If they do, make sure the connector to the Trionic box is on right.
Good luck!
