I'm dealing with this myself right now. The SHO gave out on me last week. Got
the same two codes, plus one for bad low-pump feed. Tested out both the sensors
last night, and it's the CPS that's bad, as expected.
A note about the tach loss issue: When the SHO was flaking out on me last week,
the tach would drop right to zero everytime the engine would cut out. It was
obvious that the tach signal was being completely lost. HOWEVER, when my cam
sensor died two years ago, the tach would drop to zero intermittantly, with no
relation to what the engine was actually doing. The symptom was a very short
cut out, just enough to cause the engine to "buck". Other have reported this
symptom as well for bad CMP's.
The CID does not generate the tach signal according to everything I've seen on
the service CD, but it would seem that, in some cases, maybe in certain ECU
models, it can affect the transmission of the tach signal. In this case, since
there is no 211 code, I would suspect the cam sensor, even though it seems like
it should be a crank sensor. Easy to replace, and returnable if you don't
damage it.
There are enough confusing abbreviations to go around, no need to go adding new
ones. CHK?
