Hi All,
I would like to find out if anyone else has had a similar problem and could advise.

I Have 3 error codes:

P0340 Camshaft Position Sensor ''A'' Circuit. (Intake)
P0600 Serial Communication Link
P0700 Transmission Control System (MIL Request)

The car drives ok when it starts from cold, and when diving at speed.
The issue occures when it is started for 3rd time and not cooled down.

When this malfunction happens, I have the following symptoms:

1. Auto transmission operates in emergency mode (3rd gear)
2. Instrument panel illuminates the following:
2.1. EML
2.2. ASC+T
2.3. Bake pads
2.4. Cruise control
This has been happening for the last Month.

Actions taken:

I have measured the voltage supply to both Camshaft Position Sensors (CPS) and it is 12v
The output from the exhaust CPS is 5v square wave.
The output from the intake CPS is fluctuates between 1.8 - 2.8v square wave.

Any suggestions ?
