I have a 2004 nissan sentra and it doesnt accelerate?

This code is for the throttle position sensor.

Have you had the exhaust flow tested? Especially the catalytic converter?

THE TPS SENSOR LOCATED ON THE END OF THE THROTTLE SHAFT ON THE THROTTLE BODY.

Replace just the TPS Sensor (throttle position),
not the entire throttle body, as you may have been told

Educate Yourself

Be careful,you will be sold something
you don't need

ok the fuel pressure is very good , and you replace maf sensor too,
i think 2 probable throubles, one , the catalyc converter clogged , to check remove exhaust pipe section before catalyc and run engine, its very loudness, other is tps fault, tps is throttle position sensor, located on acceleration body

good day Sir, maybe your car needs a tune up hope this tip will help you.

Your transmission might need service. Try changing your fluid and replacing the filter

very first thing i would try is a full tune up. This means the fuel filter , air filter, plugs and wires and possibly the coils. If this still does not fix it then try doing an emissions clean on it. What this does is it cleans out the intire fuel system and is very simple to do. Depending on the transmission on whether its a standard or automatic could be a bad tranny.

It appears the car may not be entering tuneup mode. warm up until temp is normal, idle stays below 1000 rpm
2000 rpm for 2 minutes
rev engine 2-3K three times
idle for one minute
turn off
disconnect tps
start
rev 2-3K three times
adjust timing

HI
did your car have (ETS) electronic throttle control system
the TPSis a part of this system
but you can test it by using diagnoses scan tool to check the TPS value when press or depress the accelerator pad.
so you can tell us the NO. of DTC for example(P0122)
