SOURCE: cnt find iat sensor on 2005 chevy cobalt ss supercharged

The IAT sensor is most of the time located along the intake tube right after Between the throttle body and MAP sensor. Just follow your air intake tube from your air filter housing to the Throttle body.
Good luck.

SOURCE: how do I change o2 sensor on 2005 cobalt

Hi, place the Cobalt in "Park" on a level surface. Allow the Chevy to sit for 10 minutes. This will allow components to cool enough to touch but still be warm, which is ideal for replacing the oxygen sensor. Open the hood of the Cobalt and identify the oxygen sensor. Look for a white, rubber, plug-type sensor on the passenger side of the exhaust manifold; this is the oxygen sensor. Use a socket wrench paired with an oxygen sensor socket to loosen the sensor. Turn the wrench counter-clockwise until the oxygen sensor is loose. Remove the sensor from the manifold by pulling it off. The sensor will come off without much force. Insert the replacement oxygen sensor onto the manifold. Secure the sensor by pushing it into place until the sensor clicks. Close the hood of the Cobalt.
Take care

SOURCE: Where is the MAP sensor

Hi, there are 3 different engines for the 2005 Cobalt. I have pasted instructions from Autozone.com for all 3 below. I recommend you run the test also pasted below before buying a new sensor. If your sensor passes the test, please get back to me with your symptoms and/or trouble code for alternate repair advice. Please let me know if you have any questions, and thanks for using FixYa.
Removal & Installation2.0L Engine
Supercharger Inlet Pressure (Scip) Sensor

Fig. Manifold Absolute Pressure (MAP) SCIP sensor location-2.0L engine

  1. Disconnect the Supercharger Inlet Pressure (SCIP) sensor harness connector.
  2. Remove the SCIP sensor (1) from the supercharger.
    WARNING: If the SCIP sensor seal is damaged, the SCIP sensor must be replaced.
  3. Inspect the seal for damage.

To install:
NOTE: Use the new SCIP sensor seal provided with the new SCIP sensor.
  1. Install the SCIP sensor (1) into the intake manifold. Tighten the bolt to 89 inch lbs. (10 Nm).
  2. Connect the SCIP sensor harness connector.
Temperature Manifold Absolute Pressure (Tmap) Sensor

Fig. Manifold Absolute Pressure (MAP) TMAP sensor location-2.0L engine

  1. Disconnect the Temperature Manifold Absolute Pressure (TMAP) sensor harness connector.
  2. Remove the TMAP sensor from the intake manifold.
    WARNING: If the TMAP sensor seal is damaged, the TMAP sensor must be replaced.
  3. Inspect the seal for damage.
To install:
NOTE: Use the new TMAP sensor seal provided with the new TMAP sensor.
  1. Install the TMAP sensor into the intake manifold. Tighten the bolt to 89 inch lbs. (10 Nm).
  2. Connect the TMAP sensor harness connector.
2.2L & 2.4L Engines
jturcotte_2010.gif

Fig. Manifold Absolute Pressure (MAP) sensor location-2.2L & 2.4L engines

  1. Remove the throttle body.
  2. Disconnect the engine harness electrical connector from the Manifold Absolute Pressure (MAP) sensor.
  3. Remove the MAP sensor and seal.

To install:
  1. Lubricate the NEW MAP sensor seal with clean engine oil.
  2. Install the MAP sensor into the intake manifold.
  3. Connect the engine harness electrical connector to the MAP sensor.
  4. Install the throttle body.
Testing
  1. Verify the integrity of the entire air induction system by inspecting for the following conditions:
    Any damage to, or hairline fractures of, the MAP sensor housing, Loose or improper installation, Any vacuum leak
  2. Verify that restrictions do not exist in the MAP sensor port or vacuum source.
  3. Determine the current vehicle testing altitude. Ignition ON, observe the scan tool BARO Sensor parameter.
  4. Use the scan tool and compare the MAP Sensor parameter to a known good vehicle, under various operating conditions.

Circuit Testing

Fig. Manifold Absolute Pressure (MAP) connector end view-2.0L & 2.2L engines
jturcotte_557.jpg

Fig. Manifold Absolute Pressure (MAP) connector end view-2.4L engine

NOTE All electrical components and accessories must be turned OFF, and allowed to power down.

  1. With the ignition OFF, disconnect the MAP harness connector at the MAP sensor.
  2. Test for less than 5 ohms of resistance between the low reference circuit terminal 2 and ground-2.0L & 2.2L (A and ground-2.4L).
    1. If greater than the specified range, test the low reference circuit for an open/high resistance.
    2. If the circuit tests normal, replace the ECM.
  3. With the ignition ON, test for 4.8-5.2 volts between the 5 volt reference circuit terminal 1 and ground-2.0L & 2.2L (C and ground-2.4L).
    1. If less than the specified range, test the 5 volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.
    2. If greater than the specified range, test the 5 volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM.
  4. Verify the scan tool MAP sensor parameter is less than 1 kPa.
    1. If greater than the specified range, test the signal circuit terminal 3-2.0L & 2.2L for a short to voltage.
    2. If the circuit tests normal, replace the ECM.
  5. Install a 3A fused jumper wire between the signal circuit terminal 3-2.0L & 2.2L and the 5 volt reference circuit terminal 1-2.0L & 2.2L. Verify the scan tool MAP sensor parameter is greater than 126 kPa.
    1. If less than the specified range, test the signal circuit terminal 3-2.0L & 2.2L for a short to ground or an open/high resistance.
    2. If the circuit tests normal, replace the ECM.
  6. If all circuits test normal, test or replace the MAP sensor.

Component Testing

NOTE You must perform the circuit/system testing, in order to verify the integrity of the MAP sensor circuits, before proceeding with the component testing.
  1. Turn ON the ignition, with the engine OFF, and remove the MAP sensor.
  2. Install a 3A fused jumper wire between the 5 volt reference circuit terminal 1-2.0L & 2.2L and the corresponding terminal of the MAP sensor.
  3. Install a jumper wire between the low reference circuit terminal 2-2.0L & 2.2L of the MAP sensor and ground.
  4. Install a jumper wire at terminal 3-2.0L & 2.2L of the MAP sensor.
  5. Connect a DMM between the jumper wire from terminal 3 of the MAP sensor and ground.
  6. Install the J 35555 to the MAP sensor vacuum port. Slowly apply vacuum to the sensor while observing the voltage on the DMM. The voltage should vary between 0-5.2 volts, without any spikes or dropouts.
  7. If the voltage is not within the specified range or is erratic, replace the MAP sensor.

Where is the speed sensor located at on a 2005 cobalt


On the passenger side. Follow the axle to the transmission. The first sensor you come to is the speed sensor.

When i went to start my 2005 chevy cobalt my T/c light came on also at the same time my abs light kicked on! what could be the problem?


Since both of these systems use the same wheel speed sensors, I would start there. The only way to not just throw parts at it by trying to guess what sensor it is would be to have a code scanner that reads ABS codes and it'll tell you exactly what sensor has failed. It would be worth it to pay a shop to scan the ABS codes so you don't have to replace all of them to make sure you get the right one.

When applying the breaks on my 2005 Chevy Cobalt it shutters and the abs light comes on .. what is the solution , do you think ?


Your brake calipers may be sticking to the brake rotor causing your abs sensor to come on. If it sticks to the rotor for an extended period of time, it could cause the caliper to actually weld itself to the rotor. I am assuming it is doing this in the front. If this is the case, you will need to replace both brake calipers, both rotors and a new set of brake pads. It is more economical to put the better parts back on it, if you can afford it.

ABS and AC lights comes on while driving


ABS and AC lights are separate issues.

ABS is usually due to a dirty or bad wheel speed sensor.
AC light has to do with the freon charge being low (r134a refrigerant pressure low).

2005 Chevy Cobalt lights turn off


automatic headlights are controlled by a photo sensor on the dash located in front of the Instrument cluster. to test the sensor try covering it and see if the headlights come on. faulty wiring in the circuit could also cause this problem. the headlights and the radio are wired together and the "auto" function will cause the radio to get brighter when its dark out, thus the combination of problems.
