Nissan Maxima Oxygen Sensor May Fail Due to Leaking Power Steering Pump

(20 reports)

Oxygen sensor failures are common due to fluid leaks from the power steering pump. The power steering pump typically leaks directly onto the sensor and causes the wiring to fail. If the leaks are not repaired when the oxygen sensor is replaced, the sensor will fail again.

Pls where is this oxygen sensor? I noticed that after my power stearing pump leaked my car has been stoping ocasionaly on the road especially when i mactch my brake or engage on low speed.Could this be as a result of oxygen sensor failure.PLs where is the sensor -
sensor keeps going out -
power steering pump leaking from suction hose o ring. as of yet has not caused o2 sensor failure but recently had to change the catalytic converters. -
not fixed yet -
Smoke pours out from under hood and right front tire well after driving and difficulty steering. thought the steering problem was from needing new coil springs that I couldn't put on right away after having new front shocks and struts on -- until billowing smoke problem. Told it was ps pump. Paid for that. Kept smoking. told today it was hose. They have hose, but now say the sensor is bad and can't fix till we get one of those. It's NOT fixed yet:( -
REPLACED 2 OF THE O2 SENSORS, (not knowing at the time I also had a transmission leak). At 150000, had work done on transmission, as front main seal replaced and pump. Now, the day I brought the maxima home from Aamco (they did tranny work), the car has difficulty starting, and after click click click, it does nothing. Currently having starter replaced, though have a feeling it is more than that. It did blow the fuse and even though put another in, dash lights up but engine will not start. Of course battery is good, checked more than once. Think Aamco bent some wires? -
