Hey Guys, I was driving my 2008 w/ 180k and at low speed acceleration (10 mph) i felt a slight shudder and the triangle of death came on. Car drove just fine and when i stopped and checked- it was the P0A7A code. Cleared the code and drove the car home. No other codes shown. This is the second time that the same things happened. Low speed acceleration--slight shudder and triangle. The first time it happened, the car drove very slow and wouldn't accelerate beyond that. I cleared the codes and for the last 1500 miles, its driven fine. This is now the second time w/ the same issue. Inverter pump and coolant was changed and i confirmed that it is working fine (i can hear/feel the noise and coolant is moving in the reservoir). Any ideas on what this could be?
