2003 Chevrolet Cobalt Questions & Answers
What does it mean when ur tc light is on in a
tc stands for traction control and usually means that something in the system is not in order, say like a wheel speed sensor. However, if the abs light goes on at the same time, it's usually a wheel speed sensor somewhere.
This could be a module or a wire to the wheel speed sensor on the tc side.
Get an ABS Brakescan Tool, like an Actron OBD-II ABS Brakescan tool to help to diagnose what is wrong.
They cost like $100 plus shipping on Amazon.com.
Water leaks on my front floorboard when my
sounds like your drain tube is clogged you should be able to see this flat nipple black in color on the passenger sideat fire wall very low or possibly under car in that area looking up,just sqeeze it it will have a **** that should open,and if debris in tube pic it out,the ac acts as a dehumidifier and creates a lot of moisture that it normally drips out under car
2003 cobalt traction control light on
traction control is controlled by a button on the dash, the only time the TC light comes on is when its shut off, indicating that you do not have traction control. try locating the button and pushing it and see if that fixes the problem, if not there is something wrong in the tc circuit (such as a wheel speed sensor) and would need further diagnosis.
How do i remove 2008
- Raise and support the vehicle.
- Place a drain pan under the oil pan drain plug.
- Remove the oil pan drain plug.
- Drain the engine oil.
- Remove the engine belt
- Remove the lower AC compressor bolt.Remove the 4 oil pan to transaxle bolts (1).
- Remove the oil pan bolts.
2007 2.2l. Why is it stuck in Drive?
Sounds like electrical problem. Is the electrical connector properly connected to the valve body on the transmission ?
Maybe a solenoid was accidently unplugged when you had the cover off.
2006 LS. Where is harness to connect camshaft position sensor?
You really need to invest in manuals for these vehicles you're working on. I don't think this engine has a camshaft position sensor, regardless of the diagram you posted. Does the engine run? Is there a connector there to rewire? Is there a port/opening to insert a camshaft position sensor into? General Motors used the 2.2L and 2.4L ecotec engines in several models from 2002 to 2006 (or later) that had no camshaft position sensors.
Hi i have a 2007 chevy colbalt when i turn the key to aux the the car starts and i can shut it off i can take the key rite out and the car will keep running
Could be bad ignition switch or some other type electrical problem . Knowing how this system works on your vehicle is the key . The ignition switch is a low voltage input to the BCM - body control module . Depending on key position the BCM knows what relays to energize and what messages to send over the GMLAN serial data net work , PCM - engine computer . Hooking up a factory or some other type professional scan tool to view ignition switch inputs to the BCM , an checking for BCM DTC'S - diagnostic trouble codes .
Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position (PNP) switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S-terminal of the starter. Ground is supplied through the engine block.
Plus you need to under stand what power modding is , because the BCM is the power mode master . This will sound funny to someone who does not know about automotive electronics .
Serial Data Gateway
The body control module (BCM) in this vehicle functions as a translator between the High and Low speed GMLAN busses. The 2 communication protocols use the BCM to translate communicated serial data messages between the control modules over the 2 serial data busses.
Power Mode Master
This vehicles body control module (BCM) functions as the power mode master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.
Power to many of this vehicle's circuits are controlled by the module that is designated the power mode master (PMM). This vehicle's PMM is the body control module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The 3-wire Ignition Switch table below illustrates the state of these inputs in correspondence to the ignition switch position:
Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs Off/Run/Crank, Accessory, and ignition 1, to distinguish the correct power mode. The ignition 1 circuit is also routed to the Run/Crank relay for relay controlled power feeds during the appropriate power mode. The BCM, after determining the desired power mode, will activate the appropriate relays for that power mode.
