Just a few weeks ago I replaced a bad ignition coil because I got the engine code P0302. I replaced the spark plugs with NGK Laser Iridium and the second Ignition coil. Now a few weeks later the Ignition coil 1 has died on me.
View 1 RepliesI have a 2002 Camry 2.4L, ECM 89666-06220, ignition coil 90919-02243. One of the coils has gone out. I got a misfire code on P303. I then moved the cylinder 3 coil to cylinder 4, cleared the code and restarted the car. The new code was P304, bad coil. I found a set of low mileage used coils, 90080-19023. The dealer says this number was one of the three options for 2002. But the pin-to-pin ohm values don't match.
The 90080-19023 pin ohms, 1-2= 348, 1-3=667, 1-4= 490, 2-3= 1100, 2-4= 912, 3-4= open. The 90919-02243 pin ohms, 1-2= 390, 1-3= 673, 1-4=940, 2-3= 1154, 2-4=1403, 3-4= open. How to successfully do this substitution and not burned up ECM ?
I'm getting Codes: P0300-306 (Misfires) and P0356.
I have researched the definitions of these codes and see that P0356 indicates an ignition coil failure on coil "F" (which would be Cylinder 6?)... but how is it possible only one coil is failing but I'm getting multiple/random misfires on all cylinders?
I've looked at the wiring diagrams and the only place that I can see a "single point failure" that can cause such a thing, would be the ECM itself...
We bought it in 2010, since then we have replaced 5 ignition coils and 2-3 batteries. Everytime the car acts up, the VSC and traction lights come on and the car starts stumbling and hesitating. The car eventually dies within a few minutes. Pull up codes and its always been an ignition coil.
Well we had all of these covered under warranty until the warranty expired in Aug. A month ago this happened again, and thought the battery was dead. It ended up being #4 coil, so I replaced.
My wife drove last week and lights came on and lights started going on/off and dinging at her and the car died. I jumped it to get it home, turned off the car and was dead. Voltage at battery was 9 volts.
I charged overnight and started the next day. I pulled negative battery cable w car running to check alternator and it stayed running, so that's good. The car is now starting just fine again.....until this happens again.....which it will.
My question is what in the heck can be making all of the coils go bad and why is the car intermittently throwing warning lights and just dying? This last time the codes pulled we P0345, PO365, PO390. All of which I don't see an explanation for.
Any easy solution to reseating this wire in the connector? It got yanked out by accident when i was removing an ignition coil under the wiring harness. 2007 camry v6
View 3 RepliesI replaced my valve cover gasket yesterday on my 2004 Camry. While putting back together, three of the tabs on the connectors for the ignition coil harness snapped off and would not stay together because of tension on the harness. I tried to zip tie them because I read that in another forum post but the clips (alligator clips?) inside the connector did not seem to be making contact with connector on top of ignition coil. The car was mis-firing and running very rough.
After much frustration, I finally removed the wires with the alligator clips from inside the connector and plugged them directly into the top of the ignition coil. Well, the car started and seems to be running/idling fine although now the Check Engine Light is on. Also, I have not driven car yet.
My question: Can I drive the car like this or will the vibration from the engine eventually loosen the connections. I am planning on ordering the connectors but they will not be in for a few days and I need to drive the car.
1.8 had recent coil pack problems? I recently had a coil pack fail in very hot weather 2 weeks ago. This week during another heat wave I believe the coil was again causing the engine to start missing. I know about VW's past reliability problems concerning coil packs and am now concerned that this may be surfacing again.
View 8 RepliesThe 2005 Avalon has 48K miles and it's been running well without any issues, until today.
Driving in city traffic, max speed is about 30 ml/h, The "Check Engine" light and the "VSC (Vehicle Slip Control) Off" lights came on. I did stop the engine, restarted after couple of minutes and the same lights stayed on. The car ran just fine, no noticeable difference in performance.
With the OBDCOM reader, the Avalon has this code:
P0351 232
P0351 Ignition coil A primary/secondary circuit malfunction
That seems to indicate a malfunction for cylinder A, or #1, ignition coil that has nothing to do with the "VSC" AFAIK. Is this a misread by OBDCOM reader, or the Avalon is confused?
The code had been reset via the OBDCOM reader, the car runs fine, neither of the lights come on now. Should I do something about coil A, or just wait until the code comes back?
My wife has an 09 Accent and a couple of days ago we were exiting the highway. As I stepped on the accelerator I noticed the engine struggle and stumble followed by the flashing MEL. I pulled into a parking lot and shut the car off and plugged the reader in to get the code but the computer already erased the code and the MEL light was extinguished and it ran fine the rest of the day. The following day my wife was driving it on the highway when the MEL light came back on but there was no associated engine roughness. I had her plug in the reader to get the code for me and it came up with P302 - misfire detected in the #2 cylinder. She didn't notice any engine roughness so I told her to drive to work but stay off the highway. She went out at lunch and the MEL light was off.
I did some research on here and the web and found the accent is known for going through ignition coils as well as a possible design flaw with the ignition wire harness that could cause it to rub and become frayed. I ordered the wire harness from our local Hyundai dealer and got an ignition coil from autozone. I also figured that I might as well get 4 spark plugs and replace them while I was at it. I got the plastic cover off and removed the 10mm bolt from the #2 ignition coil but it was wedged in there and would not budge. The coils from 1, 3, and 4 popped out with no issues. I ended up using almost a half a can of PB Blaster and 2 hours before the coil finally came out. The problem that I'm now looking at is some of the plastic from the coil remained stuck to the metal in the holder. Is there anything that I can use to clean out that metal cylinder?
After examining the spark plug from the #2 cylinder I could tell it was fouled and needed replacing but my concern is now that that new coil will get stuck in much the same manner. I'm pretty sure that the coils were WELL past due for replacement as I'm not sure when they, with the spark plugs, were replaced last. I'm pretty sure it was before my wife and I got together so that's more than the recommended 60k replacement intervals. I've ordered 3 more ignition coils to replace all of them and reset the 60k replacement interval. Since I replaced the one coil and 4 spark plugs the problem seems to have been corrected and the car is running great.
I recently had my "Service Engine Light" come on, Sunday to be exact. I went through my normal procedure of checking the fuel cap and drove several times to no avail. So today I ran by Autozone where I got the P0302 code. Now I realize I could go in for a tune up, but I'm a college student and just spent all my money on books so I'm looking for some DIY solutions before I lay down any large amounts of money. Where to start. As for a bit more background, I filled my car up with gas on Friday, the light came on Sunday and the car will shake on initial idle of the car.
View 6 RepliesI have a 2005 Santa Fe with the 3.5 with 112000 miles on it. I had the engine light come on with the code P0302 cyl #2 misfire, I got spark plugs, plug wires to do a tune up on it. I changed all of it and got it back together, started it up and it still had a miss to it. I then took the front spark plugs out and did a compression test on it. #2 was at 85, #4 was at 120, and #6 was at 160. I couldn't check the back cyls because I had already put the intake back on. I then did a wet test, and all the cyls came up to 160. So this tell me that the piston rings are bad in #2 and going bad in #4. I have kept all the oil changes up and up to this point I haven't had any trouble with it. Having this problem with there 3.5?
View 1 RepliesSo I bought my accent used a couple months ago. It is a 2007 SE 3dr 5spd manual. It ran nice during my test drive and the price was right so I bought it.
Now I'm wondering if there is any way to find out the service history on the car...at least the major one's (30k, 60k)?
I ask because recently the engine was idling a little rough and it threw a P0302 code so I changed the spark plugs and holy-cruddy-deposits-batman those things were black. Gapped the new ones and popped them in and its a noticeable difference. My CEL keeps coming on and throwing a P0496 code as well, virtually once every tank of gas. Its not the gas cap so my next step there is to check the PCSV and hoses.
With these little problems, it makes me wonder about any larger issues. I know the timing belt on these things is supposed to be replaced at 60k. Additionally I would be willing to bet that my ECM software is out of date. Would Hyundai have records for any of the big maintenance milestones since they are required for warranty work?
How much does it cost to have a dealer check your ECM software and update it if needed?
2005 3.5L FWD. 5 days ago I left the house, the engine was running smooth at idle but having hiccups when accelerating. Check engine light went on when accelerating but going off at idle. Turned around at the first stop light, parked the car home and pulled code P0302 misfire on #2 . Figured it's most likely the coil, was going to order one next day but to my surprise, no more check engine light next day and engine has been running smooth since then. Probably drove 100 miles since with no issues. I have 6 spark plugs waiting to be replaced but it's too cold to do it right now unless it's an emergency. Car has 105k miles now, spark plugs were changed at 63k. Was this just a fluke and P0302 will probably not come back or should I not risk it and just go ahead and replace the coil? If I end up replacing the coil, should I do one coil or all three?
View 22 RepliesCheck engine light came on. Codes are P0300, P0302, P0304. Plugs were previously changed. Plugs look good. Changed both coils. Light still one. Injectors also previously cleaned. What else should we check for? Valves hanging? Anything else to check for?
View 5 RepliesMy wife started our '99 Explorer last week and she said that the engine was rattling. I started it up when I got home and it sounded like something had let loose in the engine. We took it a local mechanic and he basically said that the motor was shot. I pulled the codes and it doesn't look good to me but I'm not a mechanic. Codes are:
P0301
P0302
P0303
P0173
My mother has a 1999 Camry 4cyl. that has code P0340. She says that she was driving down the road and felt like a misfire, saw the MIL turn on. When she let off the gas, she said the car stalled. It is a crank no start issue now. I was able to pull the code, but really am not familiar with Toyotas in General. I am mechanically inclined but do not have access to media such as All Data or a Service manual. Do this is most likely the sensor itself or more of an ECU issue?
View 10 RepliesWhat to do Misfire Error all cylinders also coil code P0356 . It is 2006 Avalon Ltd with 37,000 miles always maintained and all recalls completed. Is there something I missed or is this for real or could there be a common problem that is causing all the errors. Car idles ok and no problem driving below 60 mph anything over and you can fell a shutter like it will lose power.
View 14 RepliesI have come to understand that Buick LeSabres are known for their issues with their ignition modules but I'm trying to figure out the root to the problem. I have an '04 LeSabre 'Custom'. I have had all of the coils and wires replaced and the ignition module. I had to replace some of the coils and ignition module twice since. I can already feel it going again.
View 6 RepliesI'm driving down the road yesterday, and going through a intersection, get through it i'm in 3rd gear, 20mph, and my car starts to misfire, so i am like crap coil pack, i changed them all with new plugs maybe 1000 miles ago. Well I slow down so i can turn around and head back to my place slowly a mile away. and it never happens again. Now the car had just had the complete exhaust replaced last week, and literally only 9 miles put on the car before this happened. I drove 35 miles to work today, and roughly 50 miles last night after this and it has not happened anymore. Am i doomed for coil pack failure again?
View 6 RepliesI have a 2013 F150 6.2L and it wont start. It was running great and when I drove it around the corner it just shut down no clunk no warning just bam shut off. I had a engine code P0355 ( which indicated cylinder 5 coil malfunction). changed the coil and it will not fire the engine code has gone away but it will still not fire. I changed the oil just to be safe and no metal shavings in it.... Turns over just fine but will not fire. I added more fuel just to be safe ( thinking maybe I had bad fuel but that didn't work either.

The problem is there is no spark coming from the ignition coil. There is power going to the ignition coil but no spark. The car turns over but doesn't start.
I have replaced the crankshaft sensor and the Ignition Module. The wire that goes from the ignition module to the Ignition Coil has been replaced with a new wire that goes directly from the module to the coil .
Also the coil has been checked and its operating within parameters.
