2000-2011 Chevrolet Malibu

    The turn signal on my 1998 Malibu would click at random times and sometimes non-stop. I already replaced the hazard switch, which did not help. Someone suggested that it could be caused by a faulty turn signal switch. Does anyone know the part number for the turn signal switch and how the replacement could be done?

    Thank you.

    I was wondering if anyone could possibly give any advice or help. I have a 2001 Chevy Malibu and I was having fuel trouble, I replaced the Fuel pump and fuel filter. It fixed the problem, but now I’ve come to another problem. Now my check engine light is one and it gives me the error: Fuel Tank Pressure Low Voltage. What is that? What's the problem? How do I fix this? I tried clearing the diagnostic codes but this code P0452 still comes up. Please help ASAP. Thanks

    I've had a faulty turn signal in my malibu. It's not hard to change at all. I'm not sure what the part number is for the regulator but i was able to get mine at a salvage yard and replaced it and it's been fine for 3 years so far. You have to remove the cover that is covering the turn signal switch and the wiper switch. After that you may have to remove the air bag then it should allow you to have access to screws that hold the switch in place and the removal/installation is pretty simple.

    Don't have an answer for you but until someone else comes along do a google search on "P0452 - Fuel Tank Pressure Low voltage". My guess is it could be someting with the fuel pressure regulator.

    When was the fuel tank replaced and why did they think this was the problem?

    Well my fuel pump went out a few days ago, i replaced my fuel pump and i also replaced my fuel filter. Everything runs fine, its just the check engine light came on so that's when i knew something else had went wrong. Ill do the search on the P0452 and also check the fuel pressure regulator.

    Based on what you wrote about just replacing the fuel tank, I think you will be able to narrow down the problem once you do the search on P0452.

    Thanks a lot. I appreciate the help.

    Byran - Thanks for the info. It was very helpful and exactly what I was looking for! :D If you don't mind, would you advise how the cover for the turn signal switch/wiper switch could be removed? Thank you! :)

    Anyone have a clue whether the 05 - 3.5 litre is an interference or non interference type? For those who may not know what that means, an interference type engine will have problems with pistons hitting valves if a timing belt breaks. A non interference wont.

    I don't know if it's interference or not, but I do know that it has a timing chain, not a rubber belt. So the likelihood of it breaking is very low so I don't think it really matters.

    A chain drives the camshaft? I didnt know that! Are you sure?
  • mr_botsmr_bots Posts: 225
    Yep, the 3.5L LX9 engine used in the Malibu has a timing chain. Most new engines use a timing chain because they require a lot less maintenance than a belt and are less likely to break or slip.

    In addition to the inherent durability of the chain, I doubt if non ohc engines can be interference. Plus I think the chain would probably make a lot of racket before snapping. My last car (an Elantra) cost me $800 for a 60K service. I think the Chevy (supposedly) low tech engine is a big plus. That additional costly service for an OHC engine with a timing belt can pay for a lot of gas.

    Like the others said, it has a chain. I believe the only non-chain vehicle that GM has is the Aveo which like the imports required service every 50-60,000 miles. I know in the past they said to change the chains at 100,000 miles, but I am not sure if this is necessary now? Does the manual say anything?

    My S10 with over 130,000 miles has never been touched. My mechanic friend said not to worry about the Chevy V6 engine because the timing chain rarely stretches to the point that it will cause any issues or just plain come off.
  • I've got the aforementioned 97 Chevy Malibu 3.1 V6, and i'm looking for a little more horsepower. Granted, this is a family sedan, that's irrelevent. I took out the old airbox and put in a AEM air filter instead, I wanted to put in a pipe instead of the excessive stuff they have in there, but i'm not sure how to get around the mass air flow sensor. anyone have any suggestions on how to get around that? Or just get a little more horsepower out of the car using other means?
  • I was wondering what you found out, I am having the same problem?No power going to the unit and did not want to tear the whole thing apart.
  • e2helpere2helper Posts: 1,002
    A lot of times these are misdiagnosed. If you know that no power is going to it please let us know how you determined this.

    If your vehicle has cruise control does cruise control work?
  • It does have power going to the unit I just checked ti tonight. So, I determine that it is the light assy. itself.

    Yes, the cruise does work?? Why?
  • e2helpere2helper Posts: 1,002
    If cruise didn't work then I would have suspected it was something else - since it does work then I agree you are correct about CHMSL
