The trouble codes listed above are enhanced trouble codes requiring a high end professional scan tool. VW has determined that the codes may be caused by vacuum line and vacuum tee restrictions caused by debris from production or increasing mileage. The restriction affects the intake manifold operation and causes P, P faults. Or, the intake manifold flap may have become disconnected from the regulator valve.

This would require manifold replacement with an updated part. Checking procedure. Drive the vehicle to place a load on the engine. If there is a restriction, the values in field 3 will slowly increase or not increase at all. Inspect vacuum lines leading to intake manifold, and fittings, for restrictions twisted, kinked hoses or blockages caused by debris.

Reposition or clean as required. VW has also determined that the intake manifold flap can separate internally. When that happens, it will not operate correctly with the regulator valve. If the carrier plate can be pulled out, the flap has separated and the intake manifold must be replaced.

If the adaptation is not successful, the flap stop is worn internally, the intake manifold also has to be replaced. If no carrier plate, vacuum line or vacuum tee related damage is identified, and the adaptation passes, diagnose the faults using guided fault finding. This bulletin does not apply. They include wiring diagrams and technical service bulletins.

In most cases, their diagrams are right from the factory manuals. Pricing: Eautorepair. So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations. However, Alldatadiy.

Post by matti92 » Tue Apr 03, pm Hello! After being a Mk4 golf fan I decided to buy a Polo as a project. But I need some technical help please!!!

I bought a 1. The battery was completely flat and not charging so I've bought a new battery recommended for this vehicle. After much cranking the engine rang at rough idle for about a minute then stalled.

It turns over well but will not start. After studying forums and manuals, I went down checking the fuel route. The fuel priming system cannott be heard starting when the key is turned and I haven't been able to register any voltage from the pump multiplug but this might just be my lack of electrical diagnosis skills.

New fuel filter was also fitted but fuel was pulled through already filled filter using vacuum pump until I was positive I had exceeded the filters capacity and was now drawing fuel through the lines.

There were air bubbles in the lines I noticed. I have since used a generic OBD reader and produced 2 codes P Injector Circuit Malfunction Cylinder 2 P Sensor Reference Voltage "A" Circuit open With my description and these codes Im hoping a technical mind out there can put me out of my misery and help get this vehicle running!! Thanks in advance. Re: 1.

Iedere code geeft een specifiek probleem aan in het voertuig.When it comes to diagnosis a cool head must be maintained when all around appears to be crumbling. Our relationship with the customer pays dividends during diagnosis where rapport is essential when things appear to go from bad to worse. It is very easy to jump to conclusions when the evidence gathered during diagnosis points to a particular component.

It is at this stage we should take stock and step away to ponder before we commit to our diagnosis. Why not ask yourself this same question before replacing the suspect component? Asking yourself this question before committing to your diagnosis could potentially lead you to the actual cause and avoid embarrassment.

The case study below is one such example where taking a step back at the correct point in time saved the day. The vehicle in question is a 1. A basic inspection including a road test confirmed no cutting out but a clear lack of performance under acceleration.

An emission and fuel quality test proved inconclusive and so attention was focused on the detection condition of the offending MAP Sensor fault code, P The detection conditions surround the power, ground and output signals of the MAP sensor in relation to engine speed, load and throttle position. The integrity of power and ground proved stable with the engine running and so the functionality of the sensor had to be proven. A brief clean of the MAP Sensor and intake manifold port resulted in improved functionality of a component that could be attributed to the lack of power, negative fuel trim and cutting out.

A note here surrounding power, ground and signal of components such as MAP sensors:. Whilst it may be tempting to measure the signal wire only based on the fact that if the signal is OK then power and ground must be OKtrue evaluation of any component must include power, ground and signal simultaneously, unfortunately consuming three channels of your scope.

The waveform below confirms a rapid response of the MAP sensor in relation to a WOT test, accompanied with the characteristic pulsations at idle speed that can be attributed to valve open and close events. A road test once again confirmed no cutting out but the lack of power remained.

As a result further diagnosis time was now required. It is at this point customer rapport comes into play as we have used up what is fondly referred to as the Golden Hour. Authorization via the customer allowed for an additional 1 hour labour. During this time the detection conditions surrounding fault code P were pursued to include: fuel pressure, intake and exhaust integrity, 4-Gas emissions and combustion efficiency based on O2 signals.

All proved inconclusive! During the above tests it was noted that cranking time had increased before the engine would start accompanied with lumpy idle speed before stabilising. Could this be compression related as we seem to have exhausted all other possibilities? At last, a breakthrough in the diagnosis and something conclusive to follow. I have to say at this point, this is the second time Bpsc mains syllabus have used the Waveform Library during real-life diagnosis to confirm valve timing errors and both times it has proved to be successful.

Here we are looking at a small correlation error that would appear to be outside the detection of the PCM given no correlation codes have been recorded! Could this error be responsible for our Map sensor and fuel trim codes?

In order to qualify this valve timing error the rotation rulers were used to indicate degrees of crankshaft rotation between each engine position reference point missing teeth of the crankshaft sensor signal. With the rotation rulers in position the time rulers can be used to indicate not only time, but degrees of rotation with reference to the position of the rotation rulers 0 — degrees. Further analysis of the Camshaft timing error highlighted an alarming shift in the correlation during engine cranking see above.

Here we can see a shift in the relationship between the Crankshaft and Camshaft by 1. With the confirmation of shifting valve timing, the pressure transducer was installed into each cylinder for an overview of the effects on peak compression where all were found to be normal. However, an exhaust back pressure of 1. Could the exhaust back pressure be a result of shifting valve timing 1.We recommend Torque Pro. Most applications use two separate reference voltage circuits to supply a 5V current to engine and other sensors.

NOTE: Not all sensors require a reference voltage to work: two-wire fivem hide id are almost always Hall-effect sensors that generate their own signal currents by means of a magnetic field that is interrupted by a reluctor ring.

As such, these types of sensors are generally not affected by this code. The PCM interprets the changes in resistance from a sensor the Transmission Fluid Temperature sensor in this caseas degrees of temperature, and it is this voltage known as the signal voltage that is used by the PCM to make changes or adaptations to a particular system, or to recognize a condition that requires an intervention, such as initiating a fail-safe mode or other preventive measure to prevent damage to components.

This usually takes the form of other codes that refer to a specific sensor or system, but note that this is not always the case.

Be aware though that while on some applications this code will be stored on the first failure cycle, other applications may require several failure cycles before the code will set and a warning light is illuminated. The image below shows the typical appearance of wiring that had rubbed through against engine components. Therefore, it is important to clear all codes after each repair step, and to operate the vehicle normally before rescanning to see if the code returns.

Record all fault codes present, as well as all available freeze frame data. This information can be of use should an intermittent fault be diagnosed later on. NOTE: If other codes are present, note the order in which they were stored. Codes that follow P will be stored as a result of P; codes that precede P may have caused or contributed to P, and as such, these codes must be investigated and resolved before an attempt is made to diagnose P Failure to do this will almost certainly result in a misdiagnosis, wasted time, and the unnecessary replacement of parts and components.

Also be sure to investigate the relationship between code P and all codes that precede it, since resolving these codes might resolve P as well. Start the procedure by performing a thorough visual inspection of all relevant wiring, and be sure to find and inspect all related fuses and fusible links.

Replace blown fuses with their exact equivalents, but bear in mind that while blown fuses most commonly result from short circuits, fuses do not always need a reason to blow.

Long use can weaken a fuse to the point where it blows the next time current flows through it. Nonetheless, inspect all wiring for signs of damage. Make repairs or replace wiring as required. Clear all codes after repairs are complete, before operating the vehicle and rescanning the system to see if the code returns.

If no visible damage to wiring is found, prepare to perform resistance, reference voltage, continuity, and ground integrity checks on all relevant wiring and sensors.

Be sure however to disconnect all affected sensors from the PCM and other control modules to prevent damage to one or more control modules during this step. If it does not, replace the PCM. If the correct reference voltage is present at the PCM connector, follow the circuit through each sensor and control module that shares the circuit.
