SOURCE: every couple of days i get codes P0455 and P1296

I know the 1296 code is as you say, coolant temp sensor G92, but I dont feel that has any relation to the 0455 code, which refers to low evap system pressure. The fuel tank is pressurised to about 3 psi, due to its sealed construction for preventing petrol fumes reaching the outside. If the seals are not intact, the pressure will be zero, and the ecu will report code P0455. Your evap canister in the engine bay may be faulty, choked or has a tube off, or you really do have a fuel leak somewhere. The code refering to the temp sensor is seperate and you may have 2 unrelated faults. It isnt uncommon for a car to lose 2 sensors etc at the same time, or throw 2 unrelated codes. Treat each one as seperate until you know better and trace the source of each independantly.

Wont hurt the engine, its the emission control stuff that is complaining, but you can do no damage from the Evap code.

The engine temp sensor, will either make the temp gauge read wrong, which could be a problem if the motor overheats and the gauge does not indicate this - BAD - or - it will tell the ecu the car is colder than it is, and it will overfuel and idle faster than it should, not too much of a problem in itself.

I would still check out the fuel pipes etc to see if anything is leaking, as that can be very dangerous.

For peace of mind, is there anyone near you that can perform a pressure test on the gas tank?

SOURCE: vw jetta 2002 code p1296/po118

Both of these codes indicate trouble with the signal from the coolant temperature sensor.

So either the sensor is bad. The thermostat is not working properly and the coolant temperature is truly way out. The wiring to the sensor is short or open. The computer is bad and it is manifesting itself through this fault.

Does the car warm up properly? If it runs hot, or takes forever to warm up, this indicates a problem with the thermostat.

If the car runs at the proper temperature the next thing to look at is the coolant temp sensor and wiring. Some resistance values for VWs are here:

How do you fix the p1296 manufacturer specific code for a 2002 volkswagen jeta car with a 2.0 engine


P1296 is a coolant system fault code. It could be the thermostat, or the coolant temp sensor.
Either the thermostat is stuck or the coolant temp sensor is bad.
The coolant temp sensors have a reputation for going bad.

Audi a4 turbo chirps when car is started


Could be the belt(s).

If not that, could be a loose hose coming from the turbo. If it build boost and the hose is loose, it'll chirp. At least, it would on my turbo bike. Sounded like a balloon releasing air when the neck is pinched.
