How do I know if I have 24x or 58x?
One easy way to tell which reluctor wheel you have is to look at the crankshaft sensor. If it’s black you have a 24x wheel; if the sensor is gray then you have a 58x wheel.
What LS engines are 58x?
All fully Gen IV engines are 58x, and all pre-Gen IV engines (whether they are fully Gen III, or partially Gen IV) are 24x, for the crank. All 24x crank sensor engines are 1x cam gear engines. All 58x engines are 4x cam gear. Many 24x engines are DBW, including the LS1, LS6, and LS4, as well as many of the Vortecs.
Where is the Reluctor wheel on a LS engine?
GM LS engines feature a toothed reluctor wheel (also called a tone wheel or tone ring), which is press-fit onto the rear of the crankshaft. This toothed wheel is used by the crankshaft position sensor for ignition timing. In most cases, you can identify a Gen III or Gen IV by the location of the camshaft sensor.
How do you remove a Reluctor wheel?
Proper position of the wheel is essential. To avoid bending or distorting the reluctor wheel, DO NOT use a puller when removing it. We recommend heating the wheel with a torch to about 200ºF. Like all metal, the wheel will expand and you should be able to slip it off easily.
Will an LS run without cam sensor?
Will run fine without a cam sensor signal. You can experience an extended crank but the PCM can determine TDC on compression stroke eventually during cranking and once running sync everything off the crank sensor. There is no batch fire or wasted spark mode on these pcms.
When did Ls go to 58x?
Roughly in 2003, GM upgraded the LS into its Gen IV configuration with a number of changes. The upgrades included a 58x crank trigger wheel with the cam sensor moved to the timing chain cover.
What is a 24x Reluctor wheel?
The LME billet 24x reluctor wheel is a direct replacemant of the factory GM two-piece wheel found in 1997-2006 LS series engines. The rigid one piece design improves accuracy and reliabilty as opposed to the stamped and riveted OEM part.The LME reluctor installs using the same alignment tool used for the factory wheel.
What does a Reluctor do?
ignition systems …a magnetic device, called a reluctor, that is operated by the distributor shaft to produce timed electric signals, which are amplified and used to control the current to the induction coil.
What does a Reluctor ring do?
function in direct-ignition systems The reluctor ring is mounted on the crankshaft so that as the crankshaft rotates the magnetic sensor is triggered by notches in the reluctor ring. The magnetic sensor provides position information to the electronic control module, which governs ignition timing.
Will cam sensor cause no start?
If you ignore the symptoms listed here and your camshaft position sensor fails, your vehicle will not start. As a camshaft position sensor weakens, so does the data it transmits to the ECM. Eventually the data signal becomes so weak the ECM switches off fuel and spark delivery, and your engine will not start.
Where is the Reluctor located?
The reluctor ring is mounted on the crankshaft so that as the crankshaft rotates the magnetic sensor is triggered by notches in the reluctor ring. The magnetic sensor provides position information to the electronic control module, which governs ignition timing.
Can a Reluctor ring go bad?
Bent, broken or worn reluctor ring teeth can also generate a weak or unstable signal, which the ECM will be unable to analyze. Along the same lines, damaged metal parts can create debris in the form of metal filings or shavings, which the magnetic crankshaft position sensor can pick up.
Will an engine run without cam sensor?
The car doesn’t run. The engine will either start or stall if it doesn’t turn over. The engine will run poorly if the same sensor is unplugged and no signal is sent.
Can I drive without cam sensor?
What is this? Yes, it is safe to drive with a bad camshaft sensor. However, the performance of your engine will not be as good and fuel consumption may increase. If you have any trouble with your camshaft sensor, there are a few ways to test and diagnose the problem.
