I unfortunately don't have experience on this particular problem, on a 1995 Toyota Camry. One try the dealer or an auto electric shop that can trace the wiring and give you a better idea as to how to solve this problem.
Beware, that many dealers will not service cars over a certain number of years. I see that your vehicle is a 1995 which would make it 15 years old or so right now.
I know that GM won't service Cadillacs older than 10 years, and refer their customers to other technicians in the local area who have since retired from GM, or have the older testing equipment for vehicles.
It can be a journey to get an older vehicle fixed especially if the electronics is not working properly. Getting parts can be tough, as well.I unfortunately don't have experience on this particular problem, on a 1995 Toyota Camry.

Switching on the aircon will rob the engine of a handful of horses but most people most of the time won't notice. Could be the problem goes deep.
By 2007 most vehicles were digital computer controlled so it isn't easy to guess what is going on. I think you need a guy with a good scanner who knows how to use it who can gather and interpret live data.
That code relates to the transmission:
It's the sensor that sits directly on top of the transmission case.. Easy fix.
This sensor detects the rotation speed of the direct clutch drum.
By comparing the direct clutch speed signal with the vehicle speed sensor signal, the ECM detects the shift timing of the
gears and appropriately controls the engine torque and hydraulic
pressure in response to various conditions, thus performing
smooth gear shifting.

P0717 is for the transmission input speed sensor , which inturn will bring up the other code P0700 for the Trans Control Module , so i would suggest having the codes cleared and see if they come back as sometimes a glitch can occour , if codes reappear and so do the symptoms i would replace the input speed sensor , it reads the primary pulley speed and sends info to the TCM and as far as i know there are no diagnostic s to carry out as this sensor either works properly or fails so get it changed and hope its not the TCM as well, keep me posted if you wish
Code 12. RPM signal. Problem area: Loose connection, broken rpm signal wire from distributor to ecm to rpm meter, rpm meter, distributor assembly or ecm defective. Code 22. Water temperature signal. Problem area: Loose connection at water temperature sensor connector, broken wire between the sensor and the ecm, defective sensor or ecm.
No messaage of reduced engine power ? Your vehicle has electronic throttle control . Has four position sensors , two are located in the gas pedal ,an two in the throttle body . The PCM uses these sensor to know how much to open the throttle plate ,allowing more air into the engine . How did you read this code an where did you read it's definition at ? This is not a code for your vehicle . Some time cheap code readers get them wrong .

Reduced Engine Power Mode
When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
• Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
• Throttle default mode--The ECM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The ECM will perform the following actions:
- Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned off.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.
Well, a lot depends on what is causing the P0340 Diagnostic Test Code (DTC) to set.
The Camshaft Position Sensor (CMP) is a pick-up coil mounted in the outer corner of the left cylinder head just below the valve cover (assuming your Camry is equipped with a V-6...you didn't say) a one tooth signal plate is mounted to the outer camshaft. DTC P0340 sets when there is no signal recieved from the sensor by the Engine Control Module (ECM) either during engine cranking or engine running. Possible causes are: > Open or short circuit in CMP sensor circuit > Faulty CMP sensor > Defective starter > Damaged cam signal plate > Broken timing belt > Internal ECM problem Proper diagnosis required.
For 83-86 Camry, 87 corolla, 84-87 pickups and 4-runner: Code 12 = knock sensor or circuit (distributor or circuit on Cressida, Supra, and Celica 3S-GE)
87-90 Camry, all other models 88-90: Code 12 = Rpm signal/no NE or G signal to ECU within several seconds after engine is cranked.
All models from 1991 on: Code 12 = Rpm signal No "Ne" signal to the ECM within several seconds after the engine is cranked. No "G" signal to the ECM two times in Succession when engine speed is between 500 rpm and 4000 rpm.
DTC P1133 O2 BANK 1 SENSOR 1 TOO FEW TRANSITIONS Circuit Description The powertrain control module (PCM)/engine control module (ECM) constantly monitors the oxygen sensor (O2S 1) activity for 100 seconds . During the monitor period, the PCM/ECM counts the number of times that the O2S 1 switches from rich to lean and from lean to rich. With this information, a total for all switches can be determined. If the number of switches is too low, DTC P1133 will set. The lean-to-rich and the rich-to-lean are greater than 18 switches.
The PCM/ECM will turn the MIL off on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
A history DTC P1134 will clear after 80 consecutive warm-up cycles have occurred without a fault.
DTC P1133 can be cleared by using the scan tool CLEAR INFO function or by disconnecting the PCM/ECM battery feed.
Diagnostic Aids DTC P1133 is most likely caused by one of the following items:
Fuel Pressure - The system will go rich if the fuel pressure is too high. The PCM/ECM can compensate for some increase. However, if it gets too high, a DTC P1133 may set. Refer to "Fuel System Diagnosis".
Leaking injector - A leaking or malfunctioning injector can cause the system to go rich.
Manifold Absolute Pressure (MAP) sensor - An output that causes the PCM/ECM to sense a higher than normal manifold pressure (low vacuum) can cause the system to go rich. Disconnecting the MAP sensor will allow the PCM/ECM to set a fixed value for the MAP sensor. Substitute a different MAP sensor if the rich condition is gone while the sensor is disconnected.
Pressure regulator - Check for a leaking fuel pressure regulator diaphragm by checking for the presence of liquid fuel in the vacuum line to the pressure regulator.
Throttle Position (TP) sensor - An intermittent TP sensor output can cause the system to go rich due to a false indication of the engine accelerating.
O2S 1 contamination - Inspect O2S 1 for silicone contamination from fuel or improper use of RTV sealant. The sensor may have a white powdery coating and result in a high but false voltage signal (rich exhaust indication). The PCM/ECM will then reduce the amount of fuel delivered to the engine causing a severe surge or driveability problem.
This indicates a DTC Intermediate Shaft Speed Sensor "A" problem. Below are Possible Causes: Open or short in transmission revolution sensor NC (speed sensor NC)
circuit
It could be the electronic power steeirng module . With the gauges dropping out like that , the module could be bring down the data bus . Don't know how much you know about automotive electronic's an how the insturment cluster know's what speed to set speedo at an how full fuel gauge is an rpm on the tach .
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM calculates the vehicle speed based on the class 2 message indicating the wheel reference speed from the electronic brake control module (EBCM) if:
• The ECM/PCM detects a malfunction in the vehicle speed sensor circuit.
• The IPC detects a loss of class 2 communications with the ECM/PCM.
The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of class 2 communications with both the ECM/PCM.
Checking the vehicle modules for DTC'S - diagnostic trouble codes is the first place to start .
The Power Steering Control Module (PSCM) receives a class 2 vehicle speed message from the Engine Control Module (ECM) via a class 2 serial data circuit. The PSCM uses this vehicle speed message, and other inputs, to determine the desired amount of steering assist.
