Bad VCT solenoids

ANSWER : When you say you have three bad sensors I can only assume you have had them tested and the end result is three bad sensors. If they tested bad then they should be replaced. The power steering sensor senses the load of the steering on the engine so it can raise the idle during parking maneuvers. The O2 sensor is used for fuel control and it may effect engine power and fuel mileage. The camshaft sensor cay cause no starts, engine running problems and all three will turn on the check engine light.

ANSWER : Hello there. Typically jump starting a vehicle doesn’t trigger an OBD-II error code. However, one of the most common misdiagnosis issues with the P-2270 is replacing the O2 sensor before diagnosing if there are any exhaust leaks. Obviously, you’ll want to check for the exhaust leaks first, repair the damaged component, and then clear the codes before scanning the vehicle again. Sometimes the electrical harness attached to the O2 sensor is damaged or dirty which will also trigger this error code. The noise and vibration may be an indicator of a loose exhaust pipe, which may be the source of the error code staying on. If you need any help, have a technician from YourMechanic come to your home or office to diagnose your Check Engine Light and make the necessary repairs.

ANSWER : Hello. The bad coil wouldn’t have caused the crank sensor to fail. Crankshaft sensors are the most common failure on this engine so it should just be a coincidence. I would use a scan tool just to make sure that there is no rpm reading before replacing it though, as there are some other problems that can occur, but are not as likely. If you need help with this, consider having a technician from YourMechanic come to your home or office to diagnose this problem with a scan tool and replace the crankshaft sensor if necessary.

ANSWER : If you believe that your VCT solenoids or cam phasers are inoperative, I would recommend having them tested and replaced as necessary by a qualified professional in order to resolve this issue. If these parts have truely failed, it is unlikely that the vehicle will ever start without first resolving this issue.

ANSWER : Hi! That "sluggish starting" (slow cranking speed) is the most common symptom when a battery is at the end of its life. The age of your car is also just about in the normal range for how long batteries last. You are correct that it is very unlikely to be a failing starter. Here’s the good news: many automotive service businesses will test a battery for free (or close to it); it’s one of the least costly things to have wrong with your vehicle; it didn’t leave you stranded. I suggest having it tested today! If you’re trying to avoid having your car in a shop, consider YourMechanic, as a certified technician can come service your battery at your home or office to fix this issue.

ANSWER : Hey there. This may not immediately affect your car’s engine. However, it will continue to cause intermittent misfires and will gradually get worse. This may also have an impact on other parts as well since the missing cylinder will still be receiving fuel. This fuel only has one of two places it could go: either out of the exhaust as raw unburnt fuel causing damage to the catalytic converter (which may also trigger more fault codes such as the O2 sensor), OR this fuel will end up down in the oil with the oil which causes the oil to break down. When this happens, the oil loses its effectiveness on protecting other vital engine parts. For more help, I would recommend having an expert from YourMechanic come to your home to diagnose and repair the misfire for you.

ANSWER : Hi there. If you are working on an older OEM Impala, it’s more likely than not that the wiring is your problem. In some cases, when you try to start the vehicle and you get a single "click", it’s caused by the battery not having enough cranking amps. However, it can also be caused by a faulty ground, a bad starter or ignition relay or the starter itself. If you’re restoring the vehicle, it’s probably a good idea to by a new wiring kit and start from scratch, by also replacing the starter and ignition relay as well. Also, if you’ve recently painted the interior, check the ground connection; as some times fresh paint will cause a bad contact.

ANSWER : Hi there. It sounds like you may have a faulty ignition switch not returning the connection for the odometer/clock circuit or there is another underlying electrical concern possibly within the junction block. The blend door motors will not affect the odometer/clock circuits unless there is feedback in the circuit and that would present itself consistently rather than after the vehicle is started. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with an electrical problems inspection.
