      obviously you need to check your grounds on that section of the harness, and you may have burned out your primary 02 sensor.

      I'm going to take a look at the wiring diagram in the bentley manual later on, but which harness are you referencing?

I pulled out the O.B.D.II generic scan tool and was able to clear the code with no return of the light. <br> <p><B>P1473</B><br> 2001 Volkswagen Jetta GLS 1.8L, Turbo, Eng Cfg L4, Eng Des AWW <br> <br>Customer Concern: The engine is running poorly. The Check Engine Light (CEL) is on. Trouble codes P0031 (16415), P0037 (16421), P0102 (16486), P0412 (16796), P0418 (16802) and P1473 (17881). <br>Tests/Procedures: 1. Inspect fuse 43 in the fuse panel on the end of the left side of the dashboard (larger fuses, 2nd from the bottom in the row towards the rear of the car). Ensure the fuse is there and has power on both sides when the engine is running. <br>Potential Causes: Blown Fuse<br>Missing Fuse<br> <br>Tech Tips: Volkswagens may display trouble codes indicating a short to ground on the affected circuit, if the affected circuits power supply drops below a threshold voltage (typically this can occur at voltages below 10.0 Volts). Whenever multiple short to ground codes are encountered, always start diagnosis of the affected circuits by testing the common power supply for the components. In the case of fused circuits, if a blown fuse is found, testing should be performed to determine the cause of overload. <br>Diagnostic Codes: 16415, 16421, 16486, 16796, 16802, 17881, P0013, P0037, P0102, P0412, P0418, P1473 <br>Author: Steve Griff <br>Average Reported Mileage: 135407 <br> <br> <br> <br>Confirmed Fix Summary <br> <br> Confirmed Fix 1 - Fuse S243 <br> <br> <br><B>p0102</B><p><br> 2001 Volkswagen Jetta GLS 1.8L, Turbo, Eng Cfg L4, Eng Des AWW <br> <br>Customer Concern: P0102 (VW 16486), Mass Airflow (MAF) signal too low. <br>Tests/Procedures: 1. Check and verify that there are no vacuum leaks or unmetered air leaks. <p>2. Check the MAF sensor grams/second readings as follows: <p>A. Idle (about 830 RPM) 3.5 grams/sec or more (4 to 4.5 grams/sec preferred). <p>B. 2500 RPM no load, 9 to 15 grams/sec (11 to 12 grams/sec preferred). <p>C. Wide open throttle road load (drive vehicle at 45 mph in 3rd gear and perform a wide open throttle acceleration, observe maximum indicated grams/sec readings on the MAF) 90 or more grams/sec preferred. <p>D. A MAF that exhibits consistently lower than normal grams/sec readings can cause a P0102 code to set. <br>Potential Causes: Leaking Engine Vacuum<br>Defective Mass Air Flow (MAF) Sensor<br> <br>Tech Tips: Volkswagen has issued a warranty extension due to a high number of Mass Airflow Sensor failures. Mass Airflow Sensors are now warrantied for 7 years/70,000 miles on 1999 through 2001 VW vehicles. <br>Diagnostic Codes: 16486, P0102 <br>Author: Jim Newkirk <br>Average Reported Mileage: 146231 <p><br>some of the codes didnt register for a quick fix. some of the codes also came up multiple times for the same fix. try that fuse S43<p>good luck<br> <br>

      I know this is an old thread, but I wanted to post up and confirm that the same thing happened to me. I had the exact same codes. Sure enough fuse 43 was blown. It was from someone cutting the o2 sensor cable prior to replacing it. Thats what blew the fuse.

      Good reason to disconnect the battery when working on a car.
