Volkswagen Lavida traveling flameout

A mileage OBD2 Scanner of about 5500 km, 1.4TSI + DSG transmission Volkswagen sedan. Reflects the owner: the occasionally flameout of the car in normal

Fault diagnosis:

1 VAG5052 the vehicle breakdowns memory, to the engine system, there was no code.


Read engine codes:

01617 (P0651) reference voltage “B” circuit intermittent

00400 (P0190) oil rail pressure sensor “A Intermittent

00263 (P0107) manifold pressure or atmospheric pressure low-level input

00802 ignition / distributor, the engine the input circuit no signal

2. Go out obd2 software with with commissioning found no phenomenon from customers and look at the engine control fault code, the fault of the car be there, so the subsequent analysis of the code.

Vw constellation engine fault codes

3. Fault Code “B” of the reference voltage of the sensor there is a circuit, that is to the fuel rail pressure the supply of the intake air pressure and the crankshaft position sensor is Possible reason: ① The sensor’s supply line for open or short circuit; for ② engine a internal damage; the ③ engine unit Wu defective; ④ engine unit for the applicant or Poor

4. Taking into account the car time is not long, the possibility of to the engine control unit and so the focus check wiring and Check engine grounding based on circuit diagram and no abnormalities, but is still used handle (Datie households is shown in Figure 1 – Figure 3).

5. The line of the three sensors in the code using a multimeter open circuit and short is not found, but also found no of scratching. Then the sensor was measured, and also normal the circuit shown in Figure 4, as in Figure 5.

6. In order Car OBD2 to identify the point of failure, we commissioning (commissioning routes to a rugged gravel road), at the time to remove the original code. Suddenly turn off the when the brake pedal about 1 km to the light, but the engine system does not store codes; commissioning brake again, he stalled, so parking the brake master cylinder and pump check engine harness. The inspection found the car to the of “King Kong the four the total electron pump on the of the brake vacuum pump by bracket, while the brake pressure sensor harness and very close right the bracket rear, 5V power short-circuit occurred over the brake vacuum pressure

harness bracket frayed, the sensor as fault codes, (the point of failure in Figure 6) causing flameout.

Troubleshooting: repair brake pressure sensor harness,

Fault Summary: Description car diagnosis tool the case of the 5V power of the engine control although from a different but they should all fall the control unit module so we do not only check in fault sensor diagnostic instruments, inspection of the related common and wiring.
