Help me with sorting some error codes please
Hello,
i recently bought a 2002 Stilo 1.6 16V. it is on about 41,000 miles. about a week after buying it i got an engine fault light on. i bought the car from a person, not a dealer and it was recently imported, so i have no connections with previous garages. so i brought the car to a garage i trust and the guy cleared the engine fault, saying that probably the reason was bad gasoline. the codes were related to the knock sensor and some manufacture-specific code. after a week or so the engine light came on again, stayed on for about week and a half and went away by itself. i decided to do some research by myself and ordered an ELM327 reader. it just arrived tonight, so i connected it and here is the result:
P0325, P0520, P1687. after resetting these codes they reappeared right after starting the engine again. the engine failure light is off, but still these codes are there.
i did some searching and i have some suggestions pointing towards the oil pressure sensor, the knocking sensor and the throttling body, but don't know what to do - i don't want to start changing components because of error codes. the car runs well, probably sometimes there's a slight sluggishness during acceleration, which probably leads again to the throttling body. should i start checking the cable connections? where exactly are the throttling body and the knocking sensor? what about the oil pressure sensor - why there's an error code regarding it since the engine failure light is off and the oil pressure light is also off?
also i had another strange situation this morning. last night there were some severe storm and heavy rain. i used the wipes a lot. this morning when i turned the car on the wipes started by themselves! they were switched off, but still they started wiping. i restarted the engine and again they started going by themselves and stopped right at the middle of the windscreen. i tried the sprinklers, both front and back, and they went back to normal position and didn't cause any trouble any more. this evening there was rain again and they functioned without any problems. any suggestions about this strange behavior?
i very sorry for asking so much questions since i am a newcomer, but i started checking the forum as soon as i bought the car.
