The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.

When the Check Engine light (or Service Engine Soon or small picture of an engine) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.

SOURCE: Service engine code indicates EGR valve.

You could have a restriction in the egr ports. remove the valve. Plug the holes, start engine. 1 hole will be blowing out exhaust, the other will have large vacuum.

SOURCE: 2006 Chevrolet Aveo engine dash light on/off intermittently

If the light was flashing when it came on, then it means your engine is misfiring.
A solid light can mean anything.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain off. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially go on

SOURCE: chevrolet trailblazer 2006 engine spark plugs

Platinum (or more precisely-AC Delo Iridium) spark plugs. The six spark plugs are directly under each of the six coils on top of the camshaft cover. The air intake needs to be removed, then each of the 10mm bolts for the individual coils. The coils can then be removed and the spark plugs accessed.

How do I cancel the service reminder, does not respond to reset procedure. this is a 5.7l Lumina early 2006 model.


Chevrolet did not make a lumina in 2006 nor did they make a lumina with a 5.7 liter. Since your vehicle does not exist the oil reminder can not be on. Please tell us the correct Year, Make, Model, and Engine Size, we will be happy to help.

Check powertrain in Chevrolet Lumina s (V6) 2005 model


The check power train light will come on when the computer sees a problem with performance, the code you got was cam sensor,

You may have a bad cam sensor but testing will need to be done to make sure, there may be another problem causing cam code.

i would start with checking wiring to cam sensor and see what the noise is, may have bad crank pulley,

Engine light came on


Hello
When the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that powertrain control module (computer) has detected a failure somewhere in the systems it controls, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Check engine light code p1676 Chevy lumina Ltz


Trouble Code: P1676 (3.8L V6 VIN K Auto)
Evaporative Emission (EVAP) Purge Solenoid

Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
Conditions for Setting the DTC.
  • The ignition is on.
  • An improper voltage level has been detected on the output circuit which controls the EVAP purge solenoid.
  • The above conditions are present for at least 30 seconds.

Possible Causes:
  • Poor connection at the PCM. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
  • Damaged harness.
  • Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition on and observe a voltmeter connected between the EVAP purge solenoid control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP purge solenoid. A change in voltage will indicate the location of the malfunction.
