Chrysler Crossfire
Emission control system

1, Engine's MIL lamp lights up, fix:

I noticed that sometimes the engine's MIL (or CEL Check Engine Light) lamp lights up. That's a warning that there is a problem with the engine. When I read the OBD error codes it say: The fuel is lean on the bank 1 cylinders and to rich on the bank 2 cylinders.

• Error codes:

• P2096, Catalyst trim system too lean, bank 1
• P2099, Catalyst trim system too rich, bank 2

Bank 1 is where the cylinder no 1 is located on a V-engine. On a Mercedes / Chrysler engine that's on the passenger side on a left hand (not British cars) drive car.

There are a lot of things that can cause these errors. O2 sensors bad, vacuum leakage, air flow meter, temperature sensors and leaking fuel injectors. Other things as well.

The car only consume about 8.5 to 10.5 liter gasoline per 100 kilometer, so it can't be a big problem.

From an earlier data measurements I got this which show that the fuel trim values are around -10% to 0%, mean value -5%. Maybe one indication that something is wrong. The mean value should be close to 0%.

Note:
This is just an overview, you need to know a lot more to do this!
