I have a 1999 jeep grand Cherokee laredo, and I usually go from a town to another with approximately 15 dollars, this time when I went, it used up 60 dollars, I don't know what's wrong, I've got a scanner and the only codes that are appearing are the P0132: 1/1 O2 sensor shorted voltage,
P0132 1/2 O2 sensor shorted to voltage
P0132 MAP sensor voltage too high
I'm wondering if it's a sensor or something malfinctioning, I checked and it's wasting a lot of gas, while on park I accelerate it up to about 3 or 4 RPM, just a quick little press, and a whole lot of smoke comes out of the exhaust

The MAP sensor determines fuel mixture so make sure it has a good vacuum supply and the wires aren't damaged.
