With the Toyota P1300 Code, the Igniter Circuit Malfunction can cause a variety of problems with the engine. The PCM, or powertrain control module, is responsible for detecting the IGT and IGF signals, and when it doesn’t see two IGT signals after the engine has started, the P1300 code is set. The cause of this code could be due to various reasons, such as an open or shorted IGT or IGF signal circuit, a damaged or failed igniter, or a failed PCM. To help identify the source of the problem, it is important to understand the potential causes and solutions to the Toyota P1300 Code.

Causes and Solutions for Toyota P1300 Code
|IGT or IGF signal circuit is open or shorted to ground
|Inspect the IGT and IGF signal circuit for visible damage, such as corrosion, rust, or fraying.
|The Igniter is damaged or has failed
|Replace the igniter with a new one.
|PCM has failed
|Replace the PCM with a new one.
|The wiring harness is damaged
|Replace the wiring harness with a new one.
Open or Shorted IGT/IGF Signal Circuit
When a Toyota P1300 Code is set, it could be due to an open or shorted IGT or IGF signal circuit. To identify the problem’s source, inspecting the IGT and IGF signal circuit for any signs of visible damage, such as corrosion, rust, or fraying, is important. If any damage is found, it should be repaired or replaced to prevent further damage to the engine.
Damaged or Failed Igniter
A damaged or failed igniter can also cause the P1300 code. The igniter supplies the spark to the spark plugs; the engine will not start if it fails. The igniter should be replaced with a new one to fix this issue.

The PCM, or powertrain control module, is responsible for detecting the IGT and IGF signals, and when it fails, the P1300 code will be set. The PCM should be replaced with a new one to fix this issue.
Damaged Wiring Harness
Finally, the P1300 code can also be caused by a damaged wiring harness. The wiring harness connects the various engine components, and if it is damaged, the machine cannot start. The wiring harness should be replaced with a new one to fix this issue.
The Toyota P1300 Code signals various ignition issues, such as an open or shorted IGT or IGF signal circuit, a damaged or failed igniter, a failed PCM, or a damaged wiring harness. To properly diagnose the problem’s source, it is important to understand the potential causes and solutions for the Toyota P1300 Code. Once the start of the issue is identified, it can then be repaired or replaced to ensure that the engine runs properly.

FAQs About Toyota P1300 Code
What does the P1300 code indicate for a Toyota Tacoma?
The P1300 designation highlights an issue with the ignitor circuit. This specific code emerges when, during engine activity, the ECM doesn’t receive the IGF signal for a sequence of 6 IGT signals. Potential culprits include disconnection or short in the IGF or IGT circuits that link the ignitor to the ECM or a malfunctioning ignitor or ECM itself.
For a 1997 Toyota Tacoma, what does the P1300 code signify?
For that particular year’s model, the P1300 code is associated with the ignition coil, specifically No. 1. This code comes into play when the ECM doesn’t detect the IGF signal while the engine is active. The Direct Ignition System, or DIS, is designed for a single-cylinder ignition, igniting just one cylinder using one ignition coil. It’s worth noting that the ignitor is a fundamental part of the ignition coil.
When there’s an issue with an ignition coil, what code is typically triggered?
The diagnostic trouble code P0351 gets flagged, translating to “Ignition Coil ‘A’ Primary/Secondary Circuit Malfunction.” This OBD-II diagnostic trouble code suggests an issue with the ‘A’ ignition coil, specifically with the ring related to cylinder #1 or its connected circuit.
What is meant by the term “Ignition Coil ‘H’ Secondary Circuit”?
When referencing the OBD-II Code regarding decreased engine efficiency, it’s described as the Ignition Coil “H” Secondary Circuit. The ignition coil, or its counterparts, plays a pivotal role in igniting the air and fuel mixture within the engine’s combustion chambers. If these coils don’t operate optimally, the engine is bound to experience disruptions, like misfiring or stumbling.
