Chrysler Crossfire:
Emission control system


Useful information about Chrysler Crossfire and how to repair it

  1. Engine MIL lamp
  2. Fuel injectors
  3. Vacuum hose leak
  4. O2 sensors
  5. Exhaust system

This is an information page collection of what I have found and what I have repaired on my Crossfire.

I believe this information must be useful to most cars manufactured from year 1997 to maybe 2008. And if you have a Mercedes SLK R170 with a 320 engine it's almost exact the same. V engines normally have four O2 sensors and inline engines two O2 sensors.

Note:
You should not do any repair on your car if you don't have enough experience and knowledge! You use this information on your own risk! Don't blame me if something goes wrong.


3: Vacuum hose leakage:

Next thing was to see if I can find any leakage in the vacuum system. I already noticed that there were oil leakage on the right valve cover top, if oil can get out, air can get in. Modern engines with it's emission control system are very sensitive to vacuum leaks.

Check all vacuum hoses for cracks, especially at the curved paths of the hoses.

Here is the the right valve cover, I have an oil leak here. I didn't take away the whole valve cover, just the upper inspection hatch. Cleaned it from old sealing, it took a while to do this and it was cold outside that day.

Note:
There is no gasket here, just sealing compound.

Note:
The screws are made of aluminum, don't over tight, they will broke directly and then you have a serious problem! Here is two of the four screws taken away. You need space around the valve cover to do this, you have to take away the two left ignition coils. Notice the EGR valve and the O2 sensor, bank1 sensor 1 (upstream).

Oil stick O-ring

Also check the O-ring at the top of the oil stick, very common problem, replace it even if it looks fine!

Back of engine, check around the air inlet for vacuum leak, especially the big 3" O-ring between manifold and knee shaped air inlet, also the screws can be loose. You don't see it here, deep down behind the intake manifold.
