SOURCE: 2006 chevy cobalt. the key will not come out of

If the wheel is turned in either direction, pull the whell in that direction and try getting the key out. If that doesn't do it, try shifting the automatic transmission from Park back to drive, and then to park again to disengage the interlock.

SOURCE: WHERE IS THE KNOCK SENSOR ON A 2006 CHEVY COBALT

Not related to the O2 sensor. Located on the front of the engine just above the starter KNOCK SENSOR (KS) SYSTEM DESCRIPTION

PURPOSE
The knock sensor (KS) system enables the engine control module (ECM) to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation. The ECM uses the KS system to test for abnormal engine noise that may indicate detonation, also known as spark knock.

SENSOR DESCRIPTION
The knock sensor (KS) system uses a flat response 2-wire sensor. The sensor uses piezo-electric crystal technology that produces an AC voltage signal of varying amplitude and frequency based on the engine vibration, or noise, level. The amplitude and frequency are dependant upon the level of knock that the KS detects. The engine control module (ECM) receives the KS signal through a signal circuit. The KS ground is supplied by the ECM through a low reference circuit.

The ECM learns a minimum noise level, or background noise, at idle from the KS and uses calibrated values for the rest of the RPM range. The ECM uses the minimum noise level to calculate a noise channel. A normal KS signal will ride within the noise channel. As engine speed and load change, the noise channel upper and lower parameters will change to accommodate the KS signal, keeping the signal within the channel. In order to determine which cylinders are knocking, the ECM only uses KS signal information when each cylinder is near top dead center (TDC) of the firing stroke. If knock is present, the signal will range outside of the noise channel.

If the ECM has determined that knock is present, it will ****** the ignition timing to attempt to eliminate the knock. The ECM will always try to work back to a zero compensation level, or no spark ******. An abnormal KS signal will stay outside of the noise channel or will not be present. KS diagnostics are calibrated to detect faults with the KS circuitry inside the ECM, the KS wiring, the KS voltage output, or constant noise from an outside influence such as a loose/damaged component or excessive engine mechanical noise.

SOURCE: 2006 chevy cobalt the engine cooling fan is not coming on

Check with warm engine and off by touching on your radiator vents whether is in all places same temperature. If not check whether you have air in the coolant which needs bleeding,or not good coolant circulation,caused either by clogged radiator,not good water pump,or faulty thermostat.By having these things it is the possibility the fan switch not getting the correct temperature to allow the fans to start. the last thing if everything is working,the possible is the fan switch itself.

The code for my 2006 chevy cobalt is po651 voltage sensor


That code is a general location error code. According to what Ive read it has to be on a garage scanner to pin point the exact fault within that general error.

2006 Cobalt 2.2 litre has check engine light come on, then "engine disabled"


That code dsoesn't 100% mean the sensor is defective, other factors can set it. See list below.
Possible causes- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Camshaft Position Sensor
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery
P0601 CHEVROLET - Power Control Module Internal Fault

Cause: Faulty PCM. (Powertrain control module)

How to set my timing on a 2006 chevy cobalt 2.2


There is no ignition timing to set on these later model cars. The spark is controlled by sensors and the engines computer which will pulse the injectors and ignition coils. What kind of problem are you having?

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.
