Throttle Body Assembly
My check engine light is on and the code it's throwing is
P0121 - Throttle Position (TP) Sensor 1 Performance. I
took the car to a mechanic and was told that I needed a
new throttle body, pedal, and some gasket that goes with
the TB. He started the repairs and has replaced the pedal
already, however, he received a defective TB so I'm
suppose to take it back to him today, now that he has the
new TB. I'm now wondering if I even needed to replace
the pedal. Do you have to replace the pedal when you
replace a throttle body? Also, do you think that my check
engine light will go off by simply cleaning the TB? I'm
worried that this guy is taking advantage of me because
I've checked prices on a new TB and they seem to be
significantly cheaper. He is charging me $262 (for the part
only - and said that's HIS cost) but AutoZone has the
same part for $189. That wasn't even the cheapest price
that I found. They appear to range in price from $108 -
160 online. He also said that it would take an hour to
replace the part. However, yesterday, when he had to
remove the defective TB and put my old TB back in, it
only took him maybe 10 mins. I've already paid for 2.5
hours of labor for the work he did yesterday. Am I getting
ripped off?
