Question about Chrysler 2007 Sebring Touring

1 Answer

Engine knock Single female not wanting to get ripped off looking for insight please. My 2007 Sebring started making pinging/knocking sound when turning car on. Then eventually started getting louder on acceleration & losing power. Oil change less than 3 wks ago. & no check engine light on. Got so bad had to pull over. I opened the hood; no burning smell, no oil or other fluid leaks showng, belts looked fine, not the fuel pump but down a quart of oil! Just had oil change 2 weeks ago! Towed to mechanic. Is this a plug, lifter or even timing belt issue? Daddy taught me the basics but not familiar w/all the computers & sensors in these new cars

The knocking on acceleration, and the oil consumption indicate you probably have a failed big-end or conrod bearing in the engine. The classic test is to run the engine at a moderate idle and pull the plug leads off then replace them, in turn. If one shows a marked decrease in the knocking noise, that cylinder likely has a failed conrod bearing.

Positive diagnosis can be made by placing the car on a hoist and removing the sump. The suspect bearing cap is then removed. If the crankshaft bearing surface is not damaged, repair is easier, but mostly it will be scored, and then the engine has to come out.

I hope it is not this, but if so, it may be cheaper to just fit a reconditioned "short" motor.

What can cause knock sensor to get bad on 2007 ford edge


Well the knock sensor does not make any noise. It senses the vibration in the engine if there is a spark knock to let the computer know to slow down the spark timing.
You probably have a weak piston or lifter or rod bearing making the noise.

2003 chrysler concord nocks pings left side


Knocking and pinging are two separate things. "Knocking" usually refers to the sound an engine makes when internal mechanical parts, such as piston rod bearings or connecting rod bearings, begin to wear and cause a deep "knock, knock, knock" sound during engine rotation. "Pinging" refers to the tapping sound you get upon acceleration, either when using fuel that is to loo octane for the vehicle, or when static timing is set too far advanced, or when the cylinder heads are overheating due to clogged water channels or thin oil.
If you are hearing KNOCKING on the left side, it is likely time for an engine rebuild. If you are hearing PINGING, you may need a better grade of fuel, or you are way overdue for either an oil change or a major tune-up.

is the engine knocking or detonation or pinging?
is engine running lean (i sure can ping,but the knock sensor rolls back(via pcm) all spark timing, so that ping ends.

why not post symptoms first with a question,

someone broke mine

What could possible make my 2.0 motor in my Chrysler Sebring knock?


That could be a number of things. So, I would start with the easiest first. You will want to isolate the sound/knock, it may be an exhaust issue/leak/broken manifold bolt, at the exhaust manifold(s) If you check engine light is on, you will want to have a diagnostic ran, which you can perform at just about any auto parts store for free. If the light is on, you may be looking at a faulty knock sensor, and that would be the easiest to fix. If the knock sensor is not the issue, then you may be looking at something a lot more serious, like a weak oil pump, worn out camshaft, bad lifter, or even bad valves.
I hope that you have found this information useful, and if I can be of further assistance, please let me know. Thank you for using fixya! Good luck!

Have a 96 geo prizm that won't accelerate very well and is making a knocking sound any ideas?


knocking is a big thing, its a cry for help.
can be minor to horrific
knocking parked? or only driving.
in neutal or park?
knocking hot block, or cold block or both? at what RPM>/
only real oil pressure gauge works, not the idiot lamp
when the lamp comes on at 3-5psi, the war was lost.
my 96 makes 55psi cold just cranking, want a video of that?
find the knocking first.

if can ,be knocked , parked.?
id check oil pressure. real.
use a $5 stethoscope. find it.
drop all belts. to see if an accessory device knocks. (5min test max cold to start, yes, water pump dead)
PS/AC/ALT dead too.
still knock>
listen at valve cover. coming from there.
is the timing belt is old over 60k thy all shard and some knock load hitting that cover, it a for sure thing, skipping the 60k mile service point,
exhast header collerctor fange gasket , bad, allowing bang band bang as the 2 flanges pound themselves to death.
the top of the engine, see induction pips. (AIR) those mounts for sure can bang away, bolts missing.

knocking:
1 overheated the engine so bad its pinging? knocks up hills?
2: say exaclty when and not you get the knocks.

My 2007 chrysler Sebring has a whinning noise when starts. After it starts, it sounds like knocking on the left side which is the passenger side under the hood.


I have the same problem with mine. We just took it to the dealership this morning and they said it was the alternator. Said they have been seeing alot of these. My dealership wanted to charge $800 to fix it, so now my husband is trying to replace it himself.

Where is the knock sensor located and what does it look like?


Your vehicle is equipped with 2 knock sensors. They are located on the cylinder heads under the intake manifold. They look like the picture below.

NOTE: Most knock sensor codes are caused by mechanical problems with the engine like pullies that are "rattleing" or lifters that are "tapping" etc. The knock sensor does not know the difference between "ignition ping" and mechanical problems like those mentioned. Knock sensor codes set when the engine computer has retarded the ignition timing as far as it can in an effort to stop ignition ping and the knock is still present. This is usually because the problem is not caused by ignition ping.
