A knock sensor is simply a microphone that is screwed into the engine block. It is there to listen for pinging or engine "knock" that is caused by poor fuel or extreme load. When the computer hears the knock, it retards timing, which in turn reduces the tendency for knocking, however, it will reduce power to a certain extent as well. It is possible that a faulty knock sensor can be telling the computer to ****** ignition timing too much, it is also possible that there is a mechanical problem within the engine that is mimicking the sound of knocking and retarding timing as well.

    Not sure why the expletive stars went in there, it is supposed to say: "reduce ignition timing too much"

What wll cause to the engine if knock sensor malfunction


The knock sensor tells the computer when to fire the spark plugs. A bad sensor can cause a misfire,ping and lose ignition timing. If you have a bad knock sensor you should replace it ASAP as it can cause damage to the engine.

All I could find on the net as to why it may still come on is 1.It needs a slight adjustment 2.The electrical connector needs to be put on.Since you most likely put on the connector,it may just need slight adjustment.Isn't technology wonderful these days?What would Henry Ford think?lol.Here is what I found but no help really.

2005 kia spectra wont start. throwing codes 1505, 1507 and an emissions evap. short code. what is the possible fix?


P1505 - Idle-Speed Control Valve Closing Solenoid Control Circuit Electrical
P1507 - Idle-Speed Control Valve Opening Solenoid Control Circuit Signal Low

The knock sensor will cause the ignition timing to ******, which will cause a lack of power, however, it's important that the engine camshaft/crankshaft timing was set properly when rebuilding the engine, if this is off, the engine will have no power and you could set the knock sensor code.

Hope thats help.

Where is the Knock Sensor 1 located


Solution:
1. If you have to pay for a solution here on fixya, why not take it to a mechanic.
2. For the price of a live chat here on fixya for a one time solution you can purchase a complete repair manual and solve the problem yourself. Daah???? No more $20.00 piece mill each time you have a problem with your car.

I hope this eye opener will be a help to others.

I really don't expect to see this one in a post.

Acceleration issues after car warms up...


after 15 minutes the car should be out of what is called "open loop" mode, which means it runs off the computer. once warm it is in "closed loop" mode and is running off the vehicle's sensors. the first sensor I would suspect is bad is the primary oxygen sensor on the exhaust manifold. if it is not that, it is probably the coolant temp sensor or intake air temp sensor/maf sensor. likely it is the oxygen sensor, though, causing the car to run rich and therefore slow.
