The Engine Control Module adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. What causes issues and destroys the ignition coils are the Bosch platinum wire plugs. Repair short to voltage in circuit 633, retest to confirm. This first increases spark gap resistance, which reduces spark power. By the way, the gap on the old plugs was cyl. Here is a on how to do that with a.
After he cleaned out what he could, the car came up with no codes and passed inspection. I would like to add three things: 1. So far as I know this is also the part number that we use on all S-series up to 2002 not that we have many problems with those years with the coils. I believe when the code trips on the code reader, it is almost always something else. The engine may otherwise run normally. You'll probably need a flash light to do the job.
Good luck, and thank you for reading! Spec is 8K to 15K. Faulty Sensor — If the sensor coil is open or shorted, then it will generate no signal. I figure that the computer must read the resistances somehow and if they get outta spec, then it sets the code. And after looking at one, I can see why. Check your spark plug wires and route properly, and be sure that they are connected 4,1,2,3 at the coils from left to right as viewed. This is due to the polarity and amplitude of the coil during every firing event looking as if 4 cylinder is on compression.
Check for carbon or abnormal wear and proper gap 0. This fixed the battery light but the service engine light was still on and the computer was still giving a P0410 secondary air injection system malfunction code. If not, go to step 9. Perform underhood visual inspection of the ignition system, check for arcing best done in a dark area, if you are inside a garage, besure the exhaust is vented.

In turn, this may cause corrosion, open circuits, or short circuits. The coils were brand new when installed, same with the wires honestly cant see thoes being the issue and dont really have a way of testing them, they havent even been through a winter yet so cant imagine why they'd be bad already. Also, follow the wiring harness to look for damage, such as from recent engine repairs, aftermarket installations, impact damage, or rodent damage. When cranking, you should be able to see at least 20 mV. Step 6: Measure resistance of individual secondary wires. It can often end up being a wiring problem that causes P0341 in your Ion.
If your wires have more than 50K miles on them, they probably need to be replaced. So, I bought some new plugs, gapped them to. If there is some amount of resistance, suspect a short circuit. I bought used coils and ignition module from a salvage yard. Did you find a solution??? Then, because the spark is looking for an easier path, it destroys the coil winding insulation, and you wind up with weak shorted coils.
Came back when I started the car after stopping at a store. Click the reputation button near the bottom left corner of this message box. Finally I mentioned the problems to my lovely fiance, who checked the pipes and valves leading to the air pump and manifold and found out they were about 70% clogged with carbon. Turn ignition on, engine off. For example, my Buick, which had the sensor go out twice, I had well over 150k miles. Click the reputation button near the bottom left corner of this message box.
Sorry, but it's been a long time since I had to work on computer issues in cars. However, it takes far more voltage to fire a spark plug on the compression stroke then on the exhaust stroke, due to the compressed air the more air molecules, the more air the spark needs to jump, hence more resistance to spark. Ignition Coil Inspection The ignition coil can be checked using the following procedure. If there is corrosion, go to step 4 If not, go to step 5 Step 3: remove secondary wires from the coil packs. Next for the diagnostics, I'm converting this from a graphic map to a text format, so bear with me. The 1 bolt is the only thing holding the sensor on.
If the reluctor ring is rubbing on the sensor, the signal will be distorted. To find it, you must find the starter, located on the backside and under the engine. I believe your response to this error code might fix my problem. The 2 wires that go to the sensor are poorly placed. Great info - thank you for help on this apparant common issue. It is located slightly above and behind the starter.
