My marauder have two codes number one is 1151 that mean i have a proplem with o2 sensor so i bring i new one but i do not install it i leave the codes ..

i check agine i found i have two codes 1151( Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2) and 1125 this code mean the Throttle Position Sensor Intermittent so i change the sensor but i find the new one broken so i Return the old one but before i Return it i check the obd-II and i found one code P0122 Throttle Position Sensor/Switch A Circuit Low Input i think that mean the sensor is broken right ??

Have you checked for a possible vacuum leak? For the TPS, you should check the voltage at the plug, with key on, engine off, by back stabbing the harness with a volt meter. The volts should be close to 1 volt at idle position, contine to manually move throttle body to fully open position while watching your volt guage. It should be smoothly climbing the more you open the throttle and should read near 5 volts at fully open. If I recall, it is the top and bottom wires that you want to check. Been awile, search the net if you don't get a signal.
