P/S Pressure Switch P0552
Had to change the power steering pressure switch (PN: 89448-51010)on my sons 2004 Echo HB, the code P0552 was coming up once the car was started after every code clear. I tried cleaning the connector, but in the end went to the wreckers and paid $20.00 CAD for a used one. From the dealer and parts places, this little baby is $275-300 CAD. It is about $125. USD at Autozone under PN: PS442.
So changing was fairly easy with the car on ramps and accessing the switch from below with a 1 1/16 wrench. The hardest part was getting the connector to release without breaking the lock. The K Ohms readings in the amber column were alot more on the bad sensor.
