If the light illuminates, the control side of the circuit is good. I have replaced the plugs and wires and fuel filter. I will make sure it is a snug connection and a good ground. Current is applied to the primary side of the coil, which creates a magnetic field around the winding. I will report back when I have some data. If not, the problem is likely intermittent. The control module records the operating conditions at the time the diagnostic fails.
The control module writes the operating conditions to the Freeze Frame and updates the Failure Records. Chasing electrical gremlins can be challenging, but as long as you know where the fault lies in the coil circuit then youre halfway there. Disconnect the connector from the coil and inspect for corrosion. The low voltage side of the system is referred to as the primary circuit. I thought I smelled a little fuel in there. Thank you for subscribing and liking what we are doing here at The Car Doctor Channel! If you attempt to get an emissions test before resolving this issue, your vehicle will fail and you will have to get the issue resolved before paying to take it again. Watch this vid for more info.
I have the driver's side set also, but I have not replaced that set yet. I don't know where to start so i'll tell ya what I have done. If they have dedicated ground wires then I'd repeat for those too. Attach one lead of your multimeter to each terminal on the coil and set the meter to read ohms. Current technology has done away with many ignition components of the past. .
Cuz your question left me to believe you have some knowledge, but needed more in depth help. If the trouble code follows the coil pack to the new cylinder, then the ignition coil is the problem and should be replaced. Well shit that was much more of an answer than I ever gathered Ok, so then what is my option here? Then I went crazy throwing parts at it. Since the secondary winding contains many more turns of wire, output voltage is increased to thousands of volts. This diagnosis has been confirmed by three separate people. To determine whether the coil is still good, move it to another cylinder.
I have the coil pack off of the truck to get a better look at it. I have purchased from a junkyard a set of coils with the mounting bracket that holds all 4 coils to the valve cover on the passenger side, it also came with the wiring harness for the coils, the main harness was cut from the donor L33 engine The Replacement Engine. I have a Haynes Manual so I guess I need to start tracing wires. What causes the P0358 code? I checked the fuel pressure regulator. I'd connect the leads to each end of the heater wire for one O2.
So, if an individual coil is not getting power, suspect and open or short circuit in the wiring to that coil. Hope you have a scanner and good multimeter and skills. Refer to Secondary Air Injection Check Valve and Check Valve Pipe Replacement - Bank 1. Step Action Values Yes No Schematic Reference: Engine Controls Schematics 1 Did you perform the Diagnostic System Check-Engine Controls? Check for poor connection at the coil connector. Then clear the trouble codes.
YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. Where is the actual ground wire that they all connect to? I have occasionally had the P0330 where it does call for a misfire. Need help with a P0358 code? I have a P0358 code that I cannot get rid of. Is air present at the hose outlet? I appreciate kev2 the place for G102. Your coil wire harness is the vehicle original - not a cut and patch? A number of underlying problems can cause a P0358 code to be detected. The control module records the operating conditions at the time the diagnostic fails.
This did not make sense to me. Idle the engine in Closed Loop. How do you troubleshoot code P0358? First of all I replaced the plugs because the scan read random misfire. The primary side has a few hundred turns of wire, whereas the secondary side has thousands. Possible Solutions Is the engine misfiring presently? Some shops are reporting corrosion on the fuel pump ground that reduces power and fuel pressure.
Maybe connect it straight to the battery. Many times a problem can be solved with just a simple visual inspection. Thanks This did not make sense to me. Two wires are dedicated to each coil. Also, probably should've noted this, but it's a V6, not an 8.
