Experiencing issues with your 1999 Toyota Camry and encountering the 0770 OBD2 code? This code often points to problems within your vehicle’s transmission system, specifically related to the Shift Solenoid E. If you’re noticing symptoms like sputtering or a near engine stall when coming to a stop, followed by a sudden jerk, you might be dealing with the same issue many 1999 Camry owners face.
The P0770 code indicates a malfunction in the Shift Solenoid E circuit. This solenoid, sometimes referred to as the lock-up solenoid or SLT EPC, plays a crucial role in the automatic transmission’s smooth operation. When it fails, it can lead to erratic shifting and those unsettling symptoms you might be feeling.
While some might jump to conclusions about needing a complete transmission overhaul, which can be costly and time-consuming, there’s a potentially simpler and more affordable fix. One DIY approach involves targeting the likely culprit: the Shift Solenoid E itself. These solenoids can sometimes fail, and replacing the faulty one can resolve the P0770 code and restore your Camry’s smooth driving performance.
Purchasing a new Shift Solenoid E can be expensive, but exploring options like sourcing a used solenoid from a reputable auto recycler could be a budget-friendly alternative. Ensure the used part is compatible with your 1999 Camry model. Cleaning the solenoid with a Mass Air Flow (MAF) cleaner before installation is also a recommended step to ensure optimal performance.
After replacing the Shift Solenoid E, many owners have reported successful resolution of the P0770 code and a return to normal vehicle operation. The sputtering and jerking sensations during stops should disappear, and smooth shifting should be restored.
While replacing the ECU capacitors has been suggested as another potential fix by some, addressing the Shift Solenoid E directly is a worthwhile first step, especially given the code’s specific indication. This targeted approach can save you significant money and effort compared to more extensive repairs.
For those with multiple vehicles, like the owner who also had a 91 LS400, salvaged solenoids can even be repurposed for other compatible models needing shift solenoid replacements, making it an efficient and resourceful solution.
