SOURCE: 2006 Chevy cobalt just did a tune up and now have

Hi Heather , so who did the tune up ? By all these codes it mustn't run very well. What engine does yours have 2.0 l- 2.2 l - 2.4 l ?

P0128 coolant sensor An engine coolant temperature (ECT) sensor monitors the temperature of the coolant. This input is used by the powertrain control module (PCM) for engine control and as an enabling criteria for some diagnostics.
P0326 knock sensor
The knock sensor (KS) system enables the powertrain control module (PCM) to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation. The KS is located on the intake side of the engine block. The KS produces an AC voltage signal that varies depending on the vibration level during engine operation. The PCM adjusts the spark timing based on the amplitude and the frequency of the KS signal. The PCM receives the KS signal through a signal circuit. The KS ground is supplied by the PCM through a low reference circuit. The PCM learns a minimum KS noise level at idle and uses calibrated values for the rest of the RPM range. The PCM should monitor a normal KS signal within the noise channel. When the PCM detects a KS signal that varies outside of the noise channel, the PCM will retard the spark timing until the knock goes away. If the PCM is operating on large amounts of spark retard and is unable to eliminate the knock, DTC P0326 will set.
DTC P0411 : Secondary Air Injection (AIR) System Incorrect Air Flow Detected
P0496 This DTC tests for undesired intake manifold vacuum flow to the evaporative emission (EVAP) system. The control module seals the EVAP system by commanding the EVAP canister purge solenoid valve OFF and the EVAP canister vent solenoid valve ON. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system. If vacuum in the EVAP system is more than a predetermined value within a predetermined time, this DTC sets.
P1516 The commanded throttle position is compared to the actual throttle position based on accelerator pedal position (APP) and possibly other limiting factors. Both values should be within a calibrated range of each other. The engine control module (ECM) continuously monitors the commanded and actual throttle positions. This DTC sets if the values are greater than the calibrated range.
P0300 The engine control module (ECM) uses information from the crankshaft position (CKP) sensor and the ignition control (IC) module to determine when an engine misfire is occurring. By monitoring variations in the crankshaft rotation speed for each cylinder, the ECM is able to detect individual misfire events. A misfire rate that is high enough can cause the 3-way catalytic converter (TWC) to overheat under certain driving conditions. The malfunction indicator lamp (MIL) will flash ON and OFF when the conditions for TWC overheating are present. If the ECM detects a misfire rate sufficient to cause emission levels to exceed mandated standards, DTC P0300 will set.
Did you all have a lot of stuff disconnected ? What all got replaced ? What would like to know ?

Where is the idle air control valve on a 2006 cobalt


Follow your air intake boot to your throttle body, your Idle Air Control will be the sensor with two torx bits ussually 20 bit. It is the sensor with the longer flat electrical connector the one beside it with the round pushi in plug is your tps.

Need to change the knock sensor on a 2006 chev cobalt will i need to take off starter


There are 3 different engines available for 2006 Chevrolet Cobalt. [ L4-2.4L VIN B, L4-2.2L VIN F, L4-2.0L SC VIN P ] You will probably get a much more accurate answer to your question if you would take the time to mention WHICH of these engines your vehicle is equipped with.
