My service engine soon light is on and the following codes are active in my ecm "1999 Grand Prix GT with a nat aspirated 3.8"

P0141 Oxygen O2 Sensor Heater Circuit Malfunction (Bank1, Sensor2)

P0341 Camshaft Position Sensor Circuit Range/Performance

P1351 Ignition Coil Control Circuit High Voltage

Has anyone else got all three of these codes at one time? If so, what did you do to correct them?

Well #1 is the post o2 sensor. I just completly eliminated mine. The rest may have just been waiting to pop up.

How did you eliminate it, did you have to use a resistor or anything to make the ecm believe it was working correctly?

Well you can get a o2 simulator. I got a catless downpipe and its the PCM not ECM that you need to get worked out if you want to eliminate that code that way through a tune and get the codes deleted. If you have a stock downpipe tho you should just fix it. New o2 sensor NOT BOSCH.
