Nissan Repair: Nissan Frontier P1148 and P0033, nissan frontier, frontier 2

Question
I have these codes stored and the truck is a 2007 Frontier 2.5 4 cylinder with 59,000 miles. On the scanner the o2 a/f sensor is reading a rather steady .27v to .30v. When revved up a few times the sensor will read in the .82v range and the come back down to .27v when at idle. Anything common to this car and codes stored?

Answer
GM,

The P1148 is referring to being a closed loop on bank 1 and that means you need to replace the oxygen sensor on that side.  The second code, P0033, is strange since it points to a turbo/supercharger control circuit.  If your Frontier has a supercharger the waste gate is probably broken or the vacuum line is messed up, broken or come loose.  Or, you have a defective pressure sensor.  Email me back and let me know what you find.
