Toyota Code P1305 can represent a serious issue for your car, as it is an Igniter No. 2 Circuit Malfunction. In this case, the issue occurs when the engine started but the Powertrain Control Module (PCM) does not detect any IGF2 signals after detecting two IGT2 signals. It is important to note that this vehicle uses a Coil-On-Plug design Ignition System. The causes of Toyota Code P1305 are multiple, and could include an IGT or IGF signal circuit being open or shorted to ground, a damaged or failed igniter, or a failed PCM. Fortunately, there are solutions that can be implemented to fix this issue.
Causes and Solutions for Toyota Code P1305
| Cause | Solution |
|---|---|
| IGT or IGF signal circuit is open or shorted to ground | Test the circuit with an ohm meter to determine if there is a short or open in the circuit. |
| Igniter is damaged or has failed | Replace the Igniter with a new one. |
| PCM has failed | Replace the PCM with a new one. |
| Ignition System is faulty | Inspect the Ignition System and replace any faulty parts as necessary. |
Open or Short Circuit
If the IGT or IGF signal circuit is open or shorted to ground, this will prevent the PCM from detecting the IGF2 signal. To check the circuit, it is necessary to use an ohm meter to test the circuit and determine if the circuit is open or shorted. If it is open, it will need to be repaired or replaced. If it is shorted, it will need to be repaired or replaced.
Damaged or Failed Igniter
When the Igniter is damaged or has failed, it will prevent the PCM from detecting the IGF2 signal. In this case, the Igniter will need to be replaced with a new one to fix the issue.
Failed PCM
When the PCM has failed, it will prevent the PCM from detecting the IGF2 signal. As such, the PCM will need to be replaced with a new one to fix the issue.
Faulty Ignition System
If the Ignition System is faulty, it is necessary to inspect the system and replace any faulty parts as necessary. This will ensure that the system is functioning properly and the Toyota Code P1305 can be fixed.
Conclusion
In conclusion, Toyota Code P1305 can be caused by an open or short circuit in the IGT or IGF signal circuit, a damaged or failed Igniter, a failed PCM, or a faulty Ignition System. Fortunately, there are solutions that can be implemented to fix the Toyota Code P1305 issue. It is important to remember to test the circuit with an ohm meter to determine if there is a short or open in the circuit, replace the Igniter with a new one, replace the PCM with a new one, and inspect the Ignition System and replace any faulty parts as necessary.
