2003 Chevy Trailblazer LT.
Engine size = 4.2
Computer codes: p1514, p1515, p0335, p0013
Repairs for this problem = ignition coil, o2 sensor, throttle position
sensor, cam sensor
How found us = google
GM tech = mw
Question: My trailblazer will begin to hesitate then the service engine
light will come on. Then the abs light...then the engine coolant light.
When i slow down the car will stall. It will not restart right away. If i wait
about 10-15 minutes it will restart.

Answer: The first two codes are for the throttle position sensor which
is part of the throttle body assembly. Many times a good cleaning of
the carbon inside will take care of the P1514 and P1515 codes. The
P0335 crank sensor and P0013 cam position sensor are usually just
these sensors are bad. But with all these codes at the same time, and
no parts have fixed it, you may either have a wiring problem or a bad
PCM. There are a few areas under the PCM, between it and the fuse
box where wiring can break or rub against a bracket or mounting stud
and cause a short. This would explain the codes in these 3 different
systems. Clear the codes and move those harnesses around to see if
you can get it to act up. If it does then you are in the general area
and need to take the insulation apart and trace wires more closely. If
you cannot find a wiring problem, then a bad PCM should be the
problem. A scanner looking at live data stream would help allot in
diagnosing the problems.

Chevy Trailblazer Throttle Codes
2003 chevy trailblazer 4.2L.
Warning lights = Check Engine light.
Computer codes = P0222 and P0128.
Repairs: none, had a hard time starting smelled like it flooded. Now it sounds like the fan is running.
Question = If I try to replace the Throttle position sensor, do I have to replace the Throttle as well?

Answer: The throttle position sensor is not serviceable
separately, you would have to replace the entire throttle
body as an assembly. As for the other code, and the fan
running, you have a problem with the thermostat. It is most
likely stuck or was stuck at one point before. It would need
to be replaced as well, and comes with the thermostat and
aluminum housing as one piece. Fixing both of those should
take care of your problems and check engine light.
