No spark on cyl 3 and 4


What engine ? 2.2 l or 2.4 L. You don't say if any codes are set. no P0303 - P0304 cylinder's 3 & 4 misfire ? or any other ? No the cam sensor wouldn't cause just two cylinders to misfire. The PCM triggers the ICM to turn on an off coil's to build up an collapse the primary voltage inducing the secondary voltage . This engine is equipped with a non-distributor ignition system called the electronic ignition (EI) system. The primary circuit of the EI system consists of the following components:
?€¢
Two separate ignition coils

?€¢
An electronic ignition control module (ICM)

?€¢
A crankshaft position (CKP) sensor

?€¢
Related connecting wires

?€¢
The ignition control (IC) portion of the powertrain control module (PCM)
Important: The camshaft position (CMP) sensor is only used for a misfire detection. It is not part of the ignition system. !

Is there an erg valve on a honda accord 2008 4 cyl


code p0300 refers to--random/multiple cylinder/s misfire detected...Causes---spark plugs---HT leads---injectors---ignition coils ---low compression ---wiring
code p0302 refers to cylinder 2 misfire detected Causes ---engine mechanical fault---wiring---ignition/fuel system ---ECT/MAF sensors ECM
code po303 refers to cylinder 3 misfire detected Causes Engine mechanical fault---wiring---ignition/ fuel system ---injector---ECT/MAF sensor ECM The common fault to all is the fuel/system ignition
I would have the injectors checked and have a pressure test done on the fuel manifold to check pump and fuel regulator valve.

2009 saturn aura random misfire cyl 1 codes p0014,p0201,p0300


okay there are a few things that need to be checked here, seems like you were testing the wrong things, lets start with the po300, this code is for a misfire a random one which means any cylinder at a certain time has misfired which is due to the next two codes listed, the po014 which is the exhasut camshaft postion sensor system performance and the po201 injecotr control circuit for cylinder #1.

Have the injector ohm ed and the connection and wiring checked, this problem may be a bad injector or wiring to cyl # 1 and the cam sensor needs to be tested also on bank 1exhaust side. good day

What's your problem? my 2004 mercury monterey has eight codes ,po301,poo53,po106,po316,po300,po304,po305,and po306


PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.

On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.

Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.

Hope this helps...

Random misfire on all cyliner a po300 code pops up in the scanner...


It sounds like the coil is breaking down or the cam sensor may be at fault for the misfiring. Use an inline tester and connect from the coil tower to the spark plug wire to check for a good steady fire. Do this on all coil wires to spark plugs. The best time to do this is at night so you can see it fire. You may want to remove the spark plugs and inspect them for a fouling condition. If all is well then look at the cam sensor for the problem. Hope this will help you.
