What Does the P0528 Code Mean?
The P0528 code indicates that there is a problem with the fan speed sensor circuit in your vehicle. Specifically, it means that the Engine Control Module (PCM) is not receiving the expected signal from the fan speed sensor, which is crucial for regulating the cooling fan operation.
What Causes the P0528 Code?
This code can be triggered by several factors, including:
- Engine cooling fan control module failure
- Engine cooling fan failure
- Engine cooling fan relay failure
- Powertrain Control Module (PCM) failure
- Wiring issues, such as short circuits or open circuits
What Are the Symptoms of the P0528 Code?
Drivers may experience the following symptoms if the P0528 code is present:
- A/C may not operate effectively
- Cooling fans may stay on continuously
- Engine may overheat
How Serious Is the P0528 Code?
The P0528 code is classified as urgent. It indicates significant malfunctions that can potentially cause severe damage to the vehicle or pose safety risks to the driver and passengers. Immediate attention is recommended.
