2009 Toyota Prius ProblemsRestriction of the hybrid battery cooling fan may cause illumination of the Check Engine Light
The hybrid battery cooling fan may become restricted, resulting in illumination of the Check Engine Light and an associated fault code p0A82. Our technicians tell us that keeping the cooling fan clear of debris will help keep this fault code from setting and also may prolong the life of the hybrid battery.
The Check Engine Light may illuminate with a fault code P1121 stored. It is commonly caused by a failed three way coolant control valve. Valve replacement is recommended if this occurs.
The center multi-function display may failure. This is commonly caused by poorly soldered internal connection. Our technicians tell us that these display panels can be successfully repaired or reconditioned by a shop specializing in such repairs.
2009 Toyota Prius QuestionsA diagnostic test indicated a battery control module issue (PCA1F). (1 answer)
The warning light and check engine light came on once so far and not since but a diagnostic reading from Jiffy Lube indicated the battery control module (PCA1F)issue. I don't know how serious this is or whether the diagnostic tool is reliable.
It's time for my 25,000 mile scheduled maintenance and I have gone a bit over the 25,000. It will be about 25,400 when I bring it in. How much damage might I have done in those 400 miles? I am really concerned.
What would be the cost to replace the rear bumper?
2009 Toyota Prius RecallsVehicles With Added Seat Accessories May Not Have Properly Functioning Restraint Systems
Vehicles that have had accessories added to the seats such as seat heaters, seat covers or DVD headrests may not have the occupant sensor system of the passenger seat calibrated properly. This can affect passenger air bag operation in a crash. Dealers will test the sensitivity of the occupant detection sensors and recalibrate them as necessary free of charge to resolve the concern.
The affected vehicles have a steering intermediate extension shaft manufactured with metal splines that may have an insufficient hardness. Over time, the splines may wear and eventually fail resulting in a loss of steering ability, increasing the risk of a vehicle crash. Toyota dealers will inspect the extension shaft and replace if necessary.
During manufacturing, a scratch may have occurred inside of the electrically driven water (coolant) pump at the coil wire, resulting in corrosion. The corroded wire may break and the water pump could stop. The corroded coil wire could cause a short circuit in the pump resulting in a blown fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash. Dealers will replace the electric water pump to correct this concern.
