The car has shifted gear and engine reved up a couple of times while driving. If I pull over and shut off the engine, it returns to normal operating.
Yesterday engine light came on, but drove fine.
Had the codes checked out today. Gave two codes P0700 and P0715.
aa Transaxle control system fault
aa ECM received a signal that the transaxle control module has a fault
aa1 - Shortened or open circuit within transaxle
aa2 - failure of transaxle control module
aa The ECM has detected that the input speed changed suddenly
aa1 - Open or short circuit condition
aa2 - Poor electrical connection
aa3 - Faulty ISS
Is this one problem or more?
How does one effectively troubshoot to find the cause of the problem?
I would prefer to not replace everything if that can be avoided.
