Hi to all and thanks for the response my recent post,
I have a 1999 Pontiac Grand Prix and the engine light is on. Although it appears not to hamper performance, I went and bought a OBD II Tester. I now have the codes in question, they are as follows:
1. P0141, 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 3). Have no idea what 02 stands for, or (Bank 1 Sensor 3).
2. P0 137, 02 Sensor Circuit Low Voltage (Bank 1 Sensor 3).
3. P0742, Torque Converter Clutch Circuit Stuck On.
4. P1404, EGR Valve Stuck Open Or Circuit Position or EGR Closed Pintle Position.
Any idea what components are causing this problem. I am a electronic tech, so I could trouble shoot if given correct info.
Since my last post of today, I now have a new problem. On the way to pickup my girl friend from work, my transmission started to act up. When it changes gears it is rough and hesitant, but once it is in gear OK. I tend to believe that the transmission is basically OK, it is something to do with the change sequence.
As I have noted in par 3, the torque converter seems to be in difficulty, could this cause this problem.
Any info on this matter will be appreciated.
