Stalling getting P1300 code?

Hello,

Okay, I understand about putting money into a car and wanting to see it run like you intended. Fortunately, this is a fixable problem, so you should be up and running in no time. In the diagrams down below I have included the diagnostic troubleshooting flow chart for DTC P1300 from the vehicle manufacturer for your vehicle. You will need to use a Digital Multi-meter [DMM] to run these tests, so here is a link below explaining how to do so, if needed:

I have also included guides on how to find an open, and a short to power and a short to ground in the diagrams down below for you as well. Please go through these guides and get back to us with what you are able to find out.

Thanks,

Hello again,

The guides that I previously sent are from the vehicle manufacturer [Toyota], specifically for your vehicle, specifically for DTC P1300. If you follow the flowchart, which is what the technician would do if you took your vehicle into a dealership to have them fix it, you will find the problem and then be able to fix it. Please go through the guides, previously sent, and get back to us with what you are able to find out.

Thanks,

It sounds like you've already taken several steps to diagnose and address the issues with your 1996 Toyota Celica. However, troubleshooting complex car problems can be challenging, especially when you've already replaced multiple components. Here are a few additional suggestions to consider:

Check for Vacuum Leaks: Vacuum leaks can cause rough idling and stalling. Make sure all vacuum hoses are properly connected and in good condition.

Fuel System Inspection: Ensure your fuel system is functioning properly. Check the fuel pump, fuel filter, and fuel injectors for any issues. Low fuel pressure can lead to stalling.

Throttle Position Sensor (TPS): A malfunctioning TPS can cause stalling and rough idling. It's worth checking its operation and potentially replacing it if necessary.

Idle Air Control Valve (IACV): The IACV controls the engine's idle speed. If it's faulty, it could lead to stalling. Clean or replace it as needed.

Mass Airflow Sensor (MAF): A faulty MAF sensor can cause various engine issues, including stalling. Clean or replace the MAF sensor if necessary.

Cooling Fans: While the fans being stuck on might not directly cause stalling, it's worth investigating why they are behaving abnormally. This could be related to a faulty temperature sensor or wiring issue.

Electrical Grounds: Ensure that all electrical connections and grounds are secure and clean. Poor electrical connections can lead to intermittent issues.

Computer Diagnostics: With modern vehicles, many issues can be diagnosed using a diagnostic scanner. It's worth connecting one to your vehicle's OBD-II port to check for any additional trouble codes or live data that could point to the root cause of the problem.
