MS43 error code fixes?

[Braz86]

Anyone had these, and are the expensive fixes?

18 EWS Signal or Camshaft Sensor - tried to look into what this meant, and the engine shouldn't start, or stalls/misfires/lumpy. The engine runs fine and starts first time. This is reccuring as have cleared at least twice before

154 Lambda Pre Cat Bank 2 Min Limit - is this a new sensor? The readings were within range on the visual page

191 EVAP -Reed Switch Closed or Voltage Post Cat Bank 2 - guessing lambda related going off the German on the error report, but no real idea

Any help would be great!

Looked up the fault codes in my MS43 reference and got the following:

18 (P0365 and P0369). Camshaft position sensor B circuit (bank 1) or circuit intermittent (bank 1). Pull the connector off the exhaust camshaft sensor as see if there is any oil in it. If there is, check that the oil has not wicked up to the DME connections. Change the sensor anyway, use a good quality sensor as after market ones tend to cause problems.

154 (P0150) 02 sensor pre-cat (bank 2) Short to ground. Check the 02 sensor wiring or change the sensor

191 (P0161). 02 sensor heater circuit (bank 2 sensor 2). Check the heater circuit in your scanner. Most likely needs a new 02 sensor or you have a broken wire in the heater circuit.
