Common Questions
What does P0D35 mean and how does it affect my car?
The P0D35 code indicates a malfunction in the electric motor that drives the transmission fluid pump, especially in hybrid vehicles like the Chevrolet Volt. This issue can lead to poor transmission performance, increased wear on components, and ultimately higher repair costs if not addressed promptly.
What are the most common causes of P0D35 and how much does it cost to fix?
The most common cause of P0D35 is a defective electric motor for the transmission fluid pump, which can cost between $500 to $800 to replace. Other causes include wiring issues or a malfunctioning control module, which may vary in repair costs, typically ranging from $150 to $300.
Can I drive my car with P0D35 or should I stop immediately?
It's advisable to stop driving immediately if the P0D35 code is present. Continuing to drive can lead to significant transmission damage, resulting in much more costly repairs down the line.
How can I diagnose P0D35 myself using GeekOBD APP?
To diagnose P0D35 using the GeekOBD APP, first connect the app to your vehicle's OBD2 port. Use the app to read the trouble codes and analyze freeze frame data to understand the context of the fault. Check for related codes and monitor live data for the transmission system.
What vehicles are most commonly affected by P0D35?
P0D35 is most commonly found in hybrid vehicles like the Chevrolet Volt from the years 2016 to 2020. These models have been reported to experience issues with the electric motor that drives the transmission fluid pump.
How can I prevent P0D35 from happening again?
Regular maintenance of your vehicle, including checking and replacing fluid levels, inspecting electrical connections, and performing software updates, can help prevent P0D35 from recurring. Keeping the transmission system clean and addressing issues promptly is also crucial.
What is P0D35?
The diagnostic trouble code (DTC) P0D35 refers to an issue with the electric motor that drives the transmission fluid pump, specifically in hybrid vehicles like the Chevrolet Volt manufactured between 2016 to 2020. This code is triggered when the engine control module (ECM) detects a malfunction in the electric motor circuit, which can lead to inadequate fluid pressure in the transmission. In hybrid vehicles, the transmission fluid pump is crucial for maintaining the proper operation of the hybrid drive system, ensuring that the transmission operates smoothly and efficiently. If left unaddressed, this issue can result in transmission slipping, overheating, and ultimately, a more severe failure that could require expensive repairs or a complete transmission replacement. Drivers may notice a significant decline in vehicle performance, such as trouble shifting gears or a warning light on the dashboard. Addressing the P0D35 code promptly is essential to prevent progressive damage and ensure the longevity of the vehicle's transmission system.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0D35 is present:
- Check engine light remains illuminated, indicating a persistent issue that requires diagnostic attention.
- Transmission may hesitate during acceleration, leading to a feeling of loss of power or jerking as the vehicle shifts gears.
- Fuel economy might decrease by 10-20%, as the vehicle struggles to maintain optimal performance without adequate transmission fluid pressure.
- Unusual noises from the transmission, such as whining or grinding, could occur, suggesting that internal components are not lubricated properly.
- Increased engine temperature, which can be a sign of overheating due to insufficient fluid circulation in the transmission system.
Possible Causes
Most common causes of P0D35 (ordered by frequency):
- The most common cause of the P0D35 code is a faulty electric motor for the transmission fluid pump, with a likelihood of around 60%. This can be due to wear and tear, electrical shorts, or manufacturing defects.
- Another potential cause is damaged wiring or poor connections in the circuit that leads to the pump motor. This can happen due to corrosion or physical damage, which affects the electric supply.
- A third cause may involve a malfunctioning control module that fails to send the correct signals to the pump motor. Regular software updates and diagnostics can help prevent this issue.
- Less commonly, a defective transmission control module could trigger the P0D35 code, potentially leading to a cascading failure in multiple vehicle systems.
- Rarely, an internal problem within the transmission itself could be the root cause, which would require in-depth diagnostics and potentially significant repairs.
