P1299 Ford Code: An Overview

Take a look at a summary of the P1299 Ford code below:

Definition: Cylinder Head Over-temperature Protection Active
Severity: High
DIY Skill Level: Intermediate
Continue To Drive?: No
Estimated Repair Cost: $20 – $300

What Does The P1299 Mean In Ford Vehicles?

The P1299 code is triggered when the Engine Control System detects engine overheating. It specifically relates to the Cylinder Head Temperature (CHT) sensor and monitoring circuit, which informs the Powertrain Control Module (PCM) about the engine’s temperature status.

The CHT sensor measures the temperature at the cylinder head and converts it into a signal voltage that varies with temperature fluctuations. Once the PCM receives a signal indicating that the engine temperature has exceeded the critical limit set by the manufacturer, it will set the P1299 code.

When the P1299 code is set, it may trigger Ford’s fail-safe cooling system, which is an engine protection feature that activates when the engine begins, to overheat. It reduces the risk of damage by shutting down some cylinders to lower heat production and pumping air through them to aid cooling. During this mode, engine power and performance are significantly reduced.

The P1299 diagnostic trouble code (DTC) commonly occurs in Ford vehicles across several models. Some of the popular models that may encounter this code include: Escape, Fusion, F-150, Edge, Expedition, and Explorer.

This P1299 code is often accompanied by additional codes that provide more specific information about the underlying issue. Some of the codes that might be found along with P1299 include: P0128, P0117, P0118, P0125, P0126, and P2560.

How Severe Is The P1299 Code In Ford Vehicles?

The P1299 Ford DTC indicates a potentially critical issue with the engine’s cooling system, specifically related to overheating. As such, it is considered a severe code that requires immediate attention.

If you encounter the P1299 code, it is strongly recommended not to continue driving the vehicle until the underlying issue is addressed. Continuing to drive with an overheating engine can exacerbate the problem and result in costly repairs. It is advisable to safely pull over, turn off the engine, and allow it to cool down before seeking professional assistance.

What Are The Signs Of The P1299 Ford Codes?

The P1299 Ford DTC is often accompanied by the following symptoms:

Illuminated check engine light
Engine overheating
Reduced engine performance
Engine running rough or misfiring
Increased fuel consumption
Possible engine stalling or failure to start
Failsafe mode activation

What Are The Causes Of The P1299 Code In Ford?

The P1299 Ford DTC can be caused by various factors, including:

Malfunctioning CHT sensor
Faulty cooling system components (thermostat or radiator)
Low coolant level or coolant leaks
Defective water pump
Electrical issues in the CHT sensor circuit
Contaminated engine oil
Damaged cooling fan

These causes should be properly diagnosed and addressed to resolve the P1299 code.

Essential Tools And Parts

Step-by-Step Guide

Begin by using an OBD-II scanner to retrieve the P1299 code and any additional codes present. Note the freeze frame data.
Use a multimeter to check the CHT sensor circuit for electrical issues. Look for open circuits or short circuits and repair as necessary.
Check the CHT sensor for physical damage or loose connections. Replace it if necessary.
Inspect the cooling system components, including the thermostat, radiator, and water pump, for leaks, wear, or malfunction. Replace any faulty components.
Ensure the coolant level is adequate. Top up the coolant if needed and inspect for leaks.
Test the water pump for proper function. If it’s not circulating coolant effectively, replace it.
Check the engine oil for signs of contamination. If present, replace the oil and address the underlying issue.
Ensure the cooling fan operates correctly. Repair or replace the fan if needed.
After making any necessary repairs, clear the diagnostic trouble codes and perform a road test to confirm that the issue has been resolved.

DIY Repair Level And Estimated Costs

The level of DIY repair for the P1299 code varies from beginner to intermediate. If it’s a simple fix like changing the engine oil or topping up coolant, it can be a DIY task. However, more complex issues like replacing the water pump or radiator may require mechanical expertise.

Here’s an estimated cost breakdown for common repair tasks:

Repair Task	Cost Range
Wirings repair	$20 – $150
CHT Sensor replacement	$20 – $50
Thermostat replacement	$20 – $50
Radiator replacement	$100 – $300
Water pump replacement	$50 – $150
Coolant top up	$10 – $20
Engine oil change	$30 – $50

It’s crucial to diagnose the specific cause of the P1299 code accurately to avoid unnecessary expenses. If you’re uncertain about the repair, consult a professional mechanic for assistance.
