There are several limp modes on each car model.
I experienced slight limp (home) mode when my Pedal Position Sensor malfunctioned. The engine would go to default setting giving me about 80% of normal power. Enough to drive on flat freeway, but annoying in the mountain.
MAF total failure will put the car in default mode as well, so you can continue at limited performance.
The transmissions have at least couple of limp modes as well. One gives you 3rd gear, while the other might get you stuck permanently on 2nd.
