2023-2024 Dodge Hornet / Alfa Romeo Tonale MIL P0010 P0013

Owners of 2023-2024 Dodge Hornet and Alfa Romeo Tonale vehicles may encounter a specific set of symptoms indicating a potential electrical issue. This manufacturer communication, identified as S2408000083, addresses instances where the Malfunction Indicator Lamp (MIL) illuminates, the start/stop system fails to operate, and in some cases, the vehicle may not start at all. This issue is often accompanied by specific diagnostic trouble codes stored in the Powertrain Control Module (PCM).

Symptoms Owners May Notice

If you own a 2023-2024 Dodge Hornet or Alfa Romeo Tonale, you might observe one or more of the following:

• The "Malfunction Indicator Lamp (MIL) on" in your instrument cluster, commonly known as the check engine light.
• The vehicle's start/stop feature, designed to save fuel, will "Start Stop Does Not Operate" as expected.
• In more severe cases, the "Vehicle May Not Start" at all, leaving you stranded.

These symptoms, particularly the illuminated MIL and the non-functional start/stop system, are key indicators of the underlying problem described in this communication. If your 2024 Alfa Romeo Tonale MIL P0010 P0013 is on, it's important to have it diagnosed.

Fault Codes / DTCs

When these symptoms occur, a technician diagnosing the vehicle will likely find one or both of the following Diagnostic Trouble Codes (DTCs) stored in the Powertrain Control Module (PCM):

Code	Description
P0010	Bank 1 Camshaft Position 1 Actuator Control Circuit Open
P0013	Bank 2 Camshaft Position 1 Actuator Control Circuit Open

These codes indicate an open circuit within the camshaft position actuator control system, which is crucial for the engine's variable valve timing. An open circuit means that the electrical signal is not completing its path, preventing the actuator from functioning correctly.

Diagnosis and Trigger Conditions

The Powertrain Control Module (PCM) monitors various engine sensors and actuators. When it detects that the electrical circuit for the camshaft position 1 actuator on either Bank 1 or Bank 2 is open, it sets the corresponding DTC (P0010 or P0013). This open circuit condition can prevent the engine from operating efficiently, leading to the observed symptoms, including the 2024 Alfa Romeo Tonale MIL P0010 P0013 illumination and start/stop system malfunction.

Repair Procedure Summary

The repair procedure outlined in Manufacturer Communication S2408000083 is straightforward and focuses on a specific electrical connection. Technicians are instructed to:

1. Inspect the G902A ground location: This involves visually checking the ground connection for any signs of corrosion, looseness, or damage. A poor ground connection can disrupt electrical circuits and lead to the DTCs and symptoms described.
2. Clean and secure the connection as needed: If any issues are found during the inspection, the technician will clean any corrosion from the G902A ground point and ensure the connection is properly tightened and secure. A clean and secure ground is essential for reliable electrical operation.

Figures 1 and 2 in the original document provide visual guidance for locating the G902A ground point within the vehicle's engine bay, specifically for the Dodge Hornet (GG) model, which shares components with the Alfa Romeo Tonale.

Important Warnings for Owners

• This document, S2408000083, is a manufacturer communication that documents past experiences and does not authorize warranty repairs. This means that while it provides a solution, the repair may not automatically be covered under warranty, depending on your vehicle's specific warranty status and the nature of the issue.
• The repair procedure states that "No parts required" are necessary to resolve this issue. The fix primarily involves inspection, cleaning, and securing an existing electrical connection.

Owner Action

If your 2023-2024 Dodge Hornet or Alfa Romeo Tonale is exhibiting an illuminated Malfunction Indicator Lamp, a non-functional start/stop system, or difficulty starting, and you suspect this issue, it is recommended to:

1. Contact your authorized dealership: Schedule a service appointment to have your vehicle diagnosed by a qualified technician.
2. Mention the symptoms: Clearly describe the symptoms you are experiencing, such as the MIL being on, the start/stop system not working, or the vehicle failing to start.
3. Refer to Manufacturer Communication S2408000083: While not strictly necessary, mentioning this specific communication may help the technician quickly identify the potential cause and solution, especially if your 2024 Alfa Romeo Tonale MIL P0010 P0013 is present.
