double check all connections to be clean and tight, look for posible fuse, you may need an advanced scanner to check if the sensors are reading.also try resetting computer..

disconnect your battery for 10mins. this will reset all the readings. or if you have a code reader. you can reset pcm, any time you have a o2 serser code. you have to reset. check AUTO ZONE THEY CAN HELP, theyallways have a code reader handy.
