Question about 2009 Pontiac G3
Just replaced the output shaft speed sensor due to a code. The speedometer had gone out. I installed it and it will not work. Does this need to be taking back to the dealer to set up a great?
Codes do not mean a sensor is bad or needs to be replaced
Codes could mean the sensor is doing it's job & the transaxle
has a problem.
You need to google the code & do some research on diagnosing it.
Never need a dealer for anything, unless you like spending extra money vs: a local shop
That sensor is a magnetic output sensor & it gets it's field activated
from a toothed wheel inside the trans, on one of the clutch drums,
so no programming etc.

SOURCE: Coolant wiring
Ensure you are checking the right sensor.
The coolant level sensor is usually located in the coolant resevoir. It generally performs a hi/lo monitor switch function.
The coolant temperature sensor is usually located on the motor (cylinder head or thereabouts). It is a variable resistor dependant on coolant temperature.
As a quick check to identify the sensor, with engine running, short the sensor to ground. If it's the temp gauge sensor the gauge will go max high. Open circuit connection = temp low.

the oss, or vss is located on the passenger side of the car on the top of the transmission. If you jack up the car and pull the rf wheel, you will see the cv(drive shaft) going to the transmission. just past where the shaft goes in, you should see a plug on the trans. unplug it, and it should be held in by a 10mm bolt/nut. hope this helps.

I believe this is the 3800 Series II.The crankshaft position sensor is located on the passenger side of the engine,behind the crankshaft pulley for the accessory drive belt.(The reluctor that gives the sensor its signal is actually part of this pulley).I believe you can replace the sensor without removing the pulley,but I can't remember for sure(haven't replaced on of these in about 16 years).I do remember the fastest way to diagnose the sensor.All I would do is grab a can of Brakleen and go on a test drive.Drive it until it's warmed up,pull over,shut it off,wait 4 minutes(this is called heat soaking).Try to start it.If it doesn't,cool the sensor off with a couple blasts of Brakleen(it cools quickly due to fast evaporation).If it now starts up,the sensor is the culprit.
