I searched and read every thread about code 17552 and found no real answers concerning a car that only throws the one code. A lot of cars that throw multiple codes in addition to 17552 seem to have either ground problems or vacuum problems. But the ones that only throw a 17552 seem to cured with an MAF replacement. Now the story.........................
My 2000 Beetle (147K miles, bought new and no chip) threw a code last week. Vag-Com said it was Code 17552/ P1144 35-00 MAF Open or Short to Ground. I immediately thought it was connector corrosion. So I pulled the plug and recoated the contacts with OxGuard. I then cleared the code but it came back immediately. Traced wires looking for a short or open and found nothing.
Checked MAF connector and found that my Car has only three wires on the connector. In position 2 is the yellow/black; in position 3 is a green wire; position 4 has red/purple (or lavender) wire. With the key on and motor not running I checked the output of these wires at the connector. The yellow/black wire has 12V. The Green wire has 1.8V and the Red/green wire has 5V. Position one and five are unused. Note that there is no ground wire.
At this point I decided the MAF must really be bad so I installed a new one. It did not solve the problem. The code still returns immediately after it is cleared.
I bought the replace plug and wire connector kit and replaced the entire connector. It did not solve the problem. The code still returns immediately after it is cleared.
What’s next?
