2007 Chevrolet Impala - Answered Questions & Fixed issues

If your 2007 Chevy Impala is making a clicking noise before the key is even inserted into the ignition, it could be caused by a few different issues. Some potential causes include:

1. Faulty starter motor: The starter motor is responsible for starting the engine when the ignition is turned on. If the starter motor is faulty or has worn out, it may make a clicking noise as it tries to engage with the flywheel.
2. Loose or damaged starter motor relay: The starter motor relay is an electrical component that sends power to the starter motor when the ignition is turned on. If the relay is loose or damaged, it may cause a clicking noise.
3. Low battery: If the battery is low on charge or has gone bad, it may not have enough power to start the engine, causing a clicking noise.
4. Other electrical issues: There may be other electrical issues, such as a loose connection or a problem with the ignition switch, that are causing the clicking noise.

To determine the cause of the clicking noise, it is recommended to bring your vehicle to a mechanic or a dealership for further diagnosis and repair. They will be able to test the starter motor, battery, and other electrical components to determine the source of the problem and recommend the appropriate repairs.

well what engine is there. OBD2, USA, DTC error code, P0463 is a uSa federal code. all P0 are. engine 3.5 or 3.9L or 5.3L v8>? ?????? ok will reads all pages Fuel Level Sensor Circuit High Voltage Trouble Code Conditions: The ignition is ON, with the engine running. The system voltage is between 9-16 volts.<<< (means alternator not dead ) The sensor output is greater than 2.9 volts. The above condition is present for greater than 30 seconds. the sensor is inside the fuel tank. OLD SKOOL: name, is fuel lever SENDER. also makes fuel gauge work right and not lie.

First check a couple of things for me OK. First check the fuse marked fuel pump then check the fuel pump relay both of these are located on the passenger side of the engine in a box with a cover inside the cover it is marked for you if you want to pull the tank make sure the fuel level iis low then remove the two fuel hoses on the tank, then they are two straps remove them but put a support under the tank so as it does not fall on you all tis is by laying on your back and crawl under it But I thank you will fix it and not remove the tank. Good Luck

Probly need ignition tune up...test coil n module for wear. Plug cables cud b worn. Iwud hav fuelpump tested also. Get datastream or scan done by aprivate tech not adealership. It helps pinpoint furthr issues

PERHAPS IT NEEDS FILTER SERVICE

Clean the Mass Air Fuel sensor (MAF) and also the throttle body. Lots of videos online. Also a high end scan tool computer will give you live data and diagnostics when the vehicle is trying to idle.

Hi there all the things you explain are and need power to operate, make sure your battery has 12.6 volts or more and try again , if your battery doesn't have that voltage then you will need a new battery, hope this helps

only one

Use PTFE tape and fix hand tight. Check for leaks and tighten with care if needed.Steel switch and Aluminium case, not good!

07 vehicle could well be fully computerised and the fault might be associated with a black box problem. It would be unwise to do much checking without referring to a wiring diagram. In the case of a fully computerised vehicle it could be best to get a code read, though a generic obd2 code reader only reads emission related codes...

You need to change another one Iam guessing

ERIC, STOP BY YOU CHEVROLET DEALER SERVICE MANAGER WILL HELP YOU!

Someone probably forgot to finish the calibration with their scanner. If the car runs fine and everything works, I wouldn't worry too much. If the light is annoying, you will most likely have to pay someone to complete the job.

Buy a repair manual , 20 buck's auto parts store or maybe a video on youtube .

Pull off the seat back cover and look for the problem.

That would depend on what kind , how it works , power supply etc.... You mite what to have it towed to a repair shop , that is if it won't start . You could very easily make your vehicle useless . cutting wrong wires . I'm sure you have no idea of the computer systems on your car an the serial data network that all those computers share information on . How to Diagnose Controller Area Network CAN . We are here to help an give you are best suggestions . Without looking at it ,seeing how it's hooked up . I just couldn't say .

You need to get the fault codes read to get the different faults and search what the codes mean to get a suggestion of where to look as sometimes the fault is upstream of the failed component

It sounds like the electronic throttle control has a problem, you need it scanned for proper function by a either a dealer or a shop that has the correct high end scanner to do the testing, as this part costs a fortune don't just throw parts at it have the testing done.

Usually caused by a problem with the engine air intake. Check the entire intake system including the filter and throttle body, and particularly the MAP (mass air flow) sensor and the IAC (idle air control motor).

Could be a big problem. Check switch first. If switch is fine check for oil pressure using a pressure gauge plugged into oil sender hole.
