I replaced the hybrid battery in my 2011 Toyota Prius. Is it correct that I need to drive a few miles for the permanent P0A80 error code to clear? Thanks, Gerald
This can be really tricky if you didn't replace it with a brand new battery. That permanent code is a pain to clear on a gen 3 car, unless it's a new battery. Then you just drive it a bit and it clears on it's own
if it's a new battery, you just drive it a little bit. Should be cleared in a couple days. I would give it an entire weeks worth of driving before you go back and complain.
You need to complete the Confirmation Driving Pattern to clear the permanent P0A80 code. Take a look at post #53 in this thread, https://priuschat.com/index.php?posts/3595679
From Google AI: "Code C2124 on a 2011 Toyota Prius indicates a Tire Pressure Monitoring System (TPMS) malfunction. Specifically, it means the car's receiver has lost connection with Transmitter ID 4 (the fourth tire pressure sensor). This almost always happens when the internal battery inside the sensor dies after 5–10 years of use, causing it to stop broadcasting." The C2124 code is not related in any way with the hybrid battery replacement. It is a separate issue. Posted via the PriusChat mobile app.
Driving the confirmation pattern is usually a way to hurry along the forgetting of the permanent code that would happen anyway in due course of normal driving. The trouble code is detected by a self test that the car will run under certain circumstances during a drive. So the driving you do has to hit those circumstances, so the self test will run, and the test result has to be ok, and when you're not doing the confirmation pattern, just driving around normally, the test has come out ok consistently over a certain number of drives. When you do the confirmation pattern, you deliberately drive in the necessary way so the self test can run, and the car knows you're doing this on purpose and only needs to see the test turn out ok one time to forget the permanent code.
