Did you get all three of these codes from socket 2, or did the 142 come from socket 6?

Make sure the fuse is good to the o2 sensor. If it is, you can easily test the o2 sensor with a voltmeter. Peel back the rubber insulation on the single wire that is attached to it along the firewall (leaving it connnected) and probe the connector with the + probe with the - probe connected to ground. You should see the voltage sway up and down between .3 and .8 volts if the sensor is good - if it doesn't sway it needs to be replaced.
