A Jetta 5 8v 2lt came in for engine noise, what I found was that one Hydraulic lifter top was missing – the lifter is part of the follower, it is one unit, see the photo below. It is an easy job we replace the lifters and camshaft and it is a good practice to replace the oil pump also. This car has 410000 km on the clock and replacing the oil pump will be a good thing. But after we have done this the engine does not want to idle, the engine cut out and does not want to idle at all. I plug in the VAG scanner and the following code was logged:<\/p>\n

1 Fault Found:
\n16492 – Manifold \/ Barometric Pressure Sensor (G71) \/ (F96)
\nP0108 – 001 – Signal too High – Intermittent<\/p>\n

I have cleared the code but it comes back immediately, so that tells me there is a permanent fault. My next step was to unplug the sensor to check the wiring and voltage. To check the voltage at the wiring side do the following:<\/p>\n

1. Pin 3 the voltage should be closed to 5v<\/p>\n

2.Pin 1 voltage 0 -.02v<\/p>\n

3.Pin2 voltage should be .5v<\/p>\n

4. Pin Check this wire to the ECU for continuity<\/p>\n

If all these checks have been passed, my next step would be to use a scope to check the sensor operation.<\/p>\n

Actually, before I have done these checks I notice that there is something wrong with the wiring, one wire is completely broken off and the other 3 looks like something is eating the wires. See the image below.<\/p>\n

Well after reconnecting the wire and securing the other wires the fault is fixed.<\/p>\n
