My Chevy cavalier LS
2.2L Ecotech L4 134Ci vin F
TRAC OFF comes until I reset comp. Will stay off for about 10 miles then
back on. Makes tranny run rough when light comes back on, yet smooth
after resetting.
GM Computer codes = Air temp sensor in plastic air inlet tube,
Repair work done prior = replaced ignition control module on top of valve
cover,plugs and wires. Think fuel pumps now going. It has never been
replaced to my knowledge.
Work done to repair this problem = Replaced air temp sensor in the air
intake tube{right after the air filter.} I dont remember the actual code, but
thats what it pulled up as. Reset comp,both check engine, and traction off
come back on in 10 miles.
Any help will be appreciated. Got laid off and need this car to get to my new
job .Will send good tip after 1st check. Thanks
GM tech = JK
question = How to get the cars check engine Light to stay off{already
replaced the sensor that the code pulls up on a
OBD 2 diagnostic} and the
traction control to stay off after resetting computer. Also is it possible to
replace in-tank fuel pump with a in-line pump so I dont have to drop the
tank? Will in-tank allow flow through? Only have access to floor jack and
jack stands. Will be huge job that way.
The intake air temperature sensor (IAT) is a common cause for your
check engine light and causing the transmission shifting problems.
If the sensor did not fix it, then most likely one of the two wires is broken
at the connector.
The actual copper core breaks inside the colored insulation. You can
check this by pulling on each wire one at a time. If the colored insulation
stretches, the wire is broken inside and would need to be repaired.

Dont know of any conversion to put an inline fuel pump external to the
tank.
