02 sensor incorrect reading. once it is fixed you have to erase the code and drive up to 100 miles before trying for emissions again.

You have bad sycronizers in the gearbox. They are made of softer metal so they will wear out. They are used to smoothly shifte from one gear to another. How does the clutch feel? Any play in the shifter? Could be the clutch going bad, or play in the shifter also.

can only be checked with code reader

This make and model has no crash switch for the fuel pump, you may just have a defective fuel pump here.

My 4Runner did the same thing. What I did was just put a new battery in hook it up and let it honk. Put the key in the ignition and start it and it should stop. It is in alarm mode.

Your air conditioner drain duct has disconnected, just reconnect pull the rug up at the at the airconditioning there you will see the hose reconnect it

Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.

You may not be full of refrigerant... There is a low pressure switch that prevents the AC from actuating the clutch, and the reason is: IF there is not enough refrigerant, you will not be able to move oil through the system and you will have major damage...so no engauge...

Get the system checked, most likely there is a leak somewhere..

None, if it's a manual transmission. Lots, if there's a constant leak and you have the automatic version. Insufficient data presented to give a correct reply.

Hi, is this an electric fan or a clutch fan?If the former, then test the fan motor by taking a supply direct from the battery and making sure it runs. If it does, then the problem lies with the sensor in the engine which will need to be replaced. If it's a clutch fan, then the clutch unit will need to be replaced. Hope this helps!

I had a problem like this on a 1997 VW Jetta 2.0L. I suggest you obtain a multimeter, a gas pressure gauge, and a used injector from a junk yard. You need to find if the car has spark if it is getting gas and if the injector is firing. Plug a used spark plug into say # 4 spark plug wire and ground end against the manifold or other ground. Have someone crank the engine and see if there is spark. If there is spark then disconnect the electrical connector and plug in the used injector and hold in your hand. Have someone crank the engine and if it clicks as the engine revolves the injector is firing. Now if you have spark and an injector that clicks then put the pressure gauge in the upper line going to the injector manifold. Use a T so that the fuel can still flow into the manifold. If these three things check out. You need to also verify the engine is timed correctly and the timing belt did not slip a few teeth. I had a problem with my crankshaft sensor. I bought a new one and although I was getting about a .3 volt ac signal, I still had no spark at spark plugs. I wound up getting another new crankshaft sensor and read 3 volts ac from the new sensor. I then had good spark Hope this helps

P1544 = Throttle Actuation Potentiometer Signal Too High i may suggest you to have a technician to clear this code.

is the fan turning on?

Just replaced the cooling fan assembly,
