Symptoms

The primary concern is the vehicle's compliance with Federal emissions regulations. While there might not be a warning light on the dashboard, the issue could be identified during a routine inspection or an emissions test.
Diagnosis / trigger conditions
The presence of an incorrectly manufactured Crankcase Case Vent is a manufacturing defect. This issue would typically be identified by a technician during a vehicle inspection or if the vehicle fails an emissions test. The TSB indicates that the problem stems from the initial manufacturing of the engine component itself.

This repair is intended to restore the vehicle's emissions compliance.

Frequently Asked Questions
- What is a crankcase vent and why is it important for my Toyota?
- A crankcase vent, often part of the PCV (Positive Crankcase Ventilation) system, is designed to remove harmful blow-by gases from the engine's crankcase. This helps maintain engine health and, crucially, prevents these gases from escaping into the atmosphere, ensuring your vehicle complies with environmental emissions standards.
- How do I know if my 2021-2022 Toyota Camry or RAV4 has this crankcase vent issue?
- The TSB (NHTSA ID 10220222) indicates that some vehicles may have an incorrectly manufactured Crankcase Case Vent. You might not notice any symptoms. The best way to determine if your specific 2021-2022 Toyota Camry or RAV4 is affected is to contact your Toyota dealership with your VIN. They can check against the TSB records.
- Will an incorrectly manufactured crankcase vent affect my vehicle's performance?
- While the primary concern highlighted in the TSB is non-compliance with Federal emissions regulations, a faulty crankcase vent could potentially lead to other issues over time, such as oil leaks, rough idling, or reduced fuel economy. However, the TSB does not specify immediate performance impacts for the 2021-2022 Toyota Camry or RAV4.
- Is there a recall for the Toyota Camry crankcase vent issue?
- This particular issue is addressed by a Technical Service Bulletin (TSB 10220222), not a recall. TSBs are issued to help dealerships diagnose and repair common problems, often when a vehicle is still under warranty. While important, it is different from a safety recall, which typically involves a safety defect.
