Component Location

General Description

Ignition failure sensor is used to check whether the spark ignition is occurred correctly or not and also used to tachometer drive. The sensor monitors the voltage difference between a resistance which is on the battery circuit for ignition coil. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. This is confirmed for every ignition event with the crankshaft sensor and the camshaft sensor. If PCM detects a malfunction, no ignition is possible, so the engine would not start. If there is no ignition signal for a predetermined cycle for one or two ignition coils, an ignition coil circuit failure exists.

DTC Description

If there is no current at the 2 ignition coil group during 32 ignitions, the PCM determines that a fault exists and a DTC is stored.

DTC Detecting Condition

Item	Detecting Condition	Possible cause
DTC Strategy	● Current through ignition coil is monitored	● Poor connection ● Open or short in IG failure sensor circuit ● Faulty IG failure sensor ● Faulty PCM
Enable Conditions	● -
Threshold value	● No current at the 2 IG coil group during 32 ignitions
Diagnosis Time	● Continuous
MIL On Condition	● 1 driving cycle

3.

Check for open in harness (1) Ignition "OFF" (2) Disconnect IG failure sensor and PCM connector. (3) Measure resistance between terminal "2" of IG failure sensor harness connector and terminal "3/C21-2" of PCM harness connector. Specification : Approx. below 1Ω (4) Is the measured resistance within specifications? YES ▶ Go to " Component Circuit Inspection " procedure. NO ▶ Check open in harness between IG failure sensor connector and PCM connector. ▶ Repair or replace as necessary and then, go to " Verification of Vehicle Repair" procedure.

 

Verification of Vehicle Repair

After a repair, it is essential to verify that the fault has been corrected.

1.	Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed.

2.	Using a Scantool, Clear the DTCs.

3.	Operate the vehicle within conditions noted in the freeze frame data or enable conditions.

4.	Monitor that all readiness test have been verified as " Complete "

5.	Are any DTCs present ? YES ▶ Go to the applicable troubleshooting procedure. NO ▶ System is performing to specification at this time.

I don't think this is your coil as you would have a few more codes like a P0300 or even a P0350.

 

You have probably a wiring harness problem, if you replaced the IG failure sensor .

 

Or most likely a PCM problem .

 

The best way to test for this issue is to have a scope to check this fully though .

there is not much that i can do from here .

 

But remembering the last time i had this issue it was a wiring issue from the coil wiring check this well you will probably find it .

 

Otherwise there might be a reflash for this issue this you will have to ask/ring your local dealer if there is a reflash for this code.
