Question about 2002 Buick Rendezvous
The code you gave for the o2 sensor is not correct.There is no such code as p0135B.It is p0135 with no B .The usual problem is with the heater which is in the sensor itself.Unless you have wiring problems.Check the wiring and the connector and if it is all good then replace the o2 sensor1.This is the one that is on the same bank as the number 1 cylinder and on the exhaust manifold.The number one cylinder is on the back side of the motor.These are the odd number cylinders.The o2 sensor on the exhaust manifold on this head will be the one you need to replace.The p1189 is correct but there is no c at the end.The What you need to check here is the wiring and the connections also.If there is oil on the connector then clean it with brake cleaner and replace the oil sending unit.This is located next to the oil filter.Let me know what you find out.Good luck.
