If there is a Hertz signal, then replace the 2 ignition coil. We are not responsible for any actions you take on your vehicle. I also find that the most expensive place to take a Toyota for repairs after the warranty has expired is the actual Toyota dealership. Two wires are dedicated to each coil. I would definitely get regional involved, as Bitter said, dealers really don't like being put under scrutiny, especially ones with numerous customer complaints.
One is a battery feed usually from the power distribution center. Each coil is often secured by the spark plugs. Toyota revised the design of the coil to prevent these failures happening again in the future, the new part number being 90919-A2004. Possible Solutions Is the engine misfiring presently? If manipulating the wiring causes the misfire to surface, repair the wiring problem. Repair as necessary If the engine is misfiring presently, stop the engine and disconnect the 2 coil wiring connector. Enter the 5 character trouble codes in the search box and submit the search.
His dealer is unprofessional, he needs to take it to another one and explain his situation. Engine Misfire Detected on Start-up first 1000 Revolutions P0300b. If manipulating the wiring causes the misfire to surface, repair the wiring problem. In addition, even though this code calls out a specific ignition coil, checking to ensure all coils are firmly in place and show no signs of damage is recommended. The primary side has a few hundred turns of wire, whereas the secondary side has thousands.
The problem usually comes on slowly, not showing many symptoms other than a check engine light at first. This includes items such as the distributor, cap, rotor — and now even the spark plug wires. This is enough to fire the spark plugs. Now a third time - that should automatically say they mis-diagnosed the original problem. In addition to an illuminated check engine light, the most common symptom is an ignition misfire. Look up the other , please use the search box.
Attach one lead of your multimeter to each terminal on the coil and set the meter to read ohms. We will make a video soon to show you how to find the cylinder order on your engine. If it is B1391 that would be the only code with 1391 for your vehicle. Edited July 28, 2010 by mthnrd Well, picked up the Corolla and was told I was good to go. If manipulating the wiring causes the misfire to surface, repair the wiring problem. Have an assistant crank the engine. It eliminates the need for spark plug wires by putting the coil right above the sparkplug.
I don't have any proof! Repair as necessary If the engine is misfiring presently, stop the engine and disconnect the 2 coil wiring connector. Personally, should have never gotten to the second coil replacement event - but that is just me. Or malfuntion of the ignition coil. It eliminates the need for spark plug wires by putting the coil right above the sparkplug. Open circuits in the ignition coil circuit are often found on top of the engine due to wildlife damage.
I'm using iridium spark plugs and wondering if that is my problem. Solutions Is the engine misfiring presently? If there is any significant voltage on that wire then there is a short to voltage somewhere. Typical readings should be 6,000 to 15,000 ohms. Started the sputtering again, this time worse than before. If continuity is present, then check for resistance between ground and the ignition coil connector.
Check the condition of the Spark plug, Spark plug Wires. Then, they will inspect the wires that connect the coil packs for signs of corrosion, fraying and even melting. In most cases, if a crack occurs at certain solder points or on certain varistors, the check engine may illuminate, harsh shifting could result, or the engine may not start. The way it works is it eliminates the need for spark plug wires as it puts coil above the sparkplug. If there is a Hertz signal, then replace the 2 ignition coil.
Another dealership will diagnose the problem - but not for free. If there is no continuity repair the open or short to ground in the circuit. And in this case, the cylinders have to work twice as hard to run the vehicle, putting stress the cylinder and all involved components such as spark plugs, piston rings, and coil packs, causing them to wear faster. B1391 - Oil Level Switch Circuit Failure C1391 - Not a valid obd code. If the voltage in the ignition control circuit for ignition coil C varies by more than 10% from allowed parameters, set by each automaker, a malfunction is noted and a P0353 code is stored. One is a battery feed usually from the power distribution center.
We are not responsible for any actions you take on your vehicle. Let's see how long before the sputtering returns. I think the dealer was trying to stall fixing the problem until after the 36000 mile warranty and get my money. This test checks the resistance of the coil. What causes the P0353 code? Current technology has done away with many ignition components of the past.
