In practical terms, reference voltages usually 5 voltscan be seen as the power supply that some sensors use to generate a signal voltage. While the above example is an oversimplification, it serves to illustrate the point that the PCM uses reference voltages to monitor both the operation of a particular component like a sensorand the system that depends on the efficient operation of that sensor to function as intended.

As a practical matter, the PCM generates two stabilized 5-volt reference voltage circuits, with each circuit serving different sensors. Typically, reference voltage circuit 1 would serve the following sensors. NOTE: There are differences between manufacturers on which sensors are served by which reference voltage circuit.

Always refer to the manual for the application being worked on for detailed information on which reference voltage circuit serves which sensors to avoid confusion, misdiagnoses, and the almost certain unnecessary replacement of parts and components.

However, the disadvantage of using only two reference voltage circuits to serve multiple sensors involves the fact that a failure in one reference voltage circuit affects all the other sensors that are served by that failed reference voltage circuit.

This also means that one or more signals returned to the PCM by one or more sensors may be incorrect, invalid, implausible, or otherwise out of accepted parameters, even though the affected signal circuits may be in perfect working condition. The image below shows damage caused to wiring that had been chafing against engine components, which is a common cause of open circuits.

The possible causes of open circuits are any and varied, but some common causes could include the following. Refer to the manual for the application being worked on for detailed information on the symptoms that are most likely to be present on the application when P is present. Note however, that while other codes may be present along with P, it must be remembered that these codes and their associated symptoms, which could include serious driveability issues, are almost certainly the result of P, which means that P MUST be resolved first.

Record all fault codes present, as well as all freeze frame data. This information can be of use should an intermittent fault be diagnosed later on. NOTE: On some applications, a short circuit to battery voltage in the signal circuit of some sensors can cause P to set as well. Thus, if codes relating to short circuits to voltage are present, consult the manual on the relationship between such codes and P before starting a diagnostic procedure to save time, and to prevent possible misdiagnoses.

Also, use this opportunity to determine to routing, color-coding, function, and location of all relevant wiring before unplugging, disconnecting, or testing anything. It is also a good idea to trace and mark all relevant wiring on the wiring diagram at this point. Doing this now will save time and possible confusion later when individual wires have to be traced while looking for the cause of the open circuit. Typical values for this circuit range between 4.This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. The P indicates that the sensor reference voltage B circuit is open. This code applies to all manufacturers. This generic code shows that there is some type of fault in the sensor reference voltage "B", and is detected by one of the other sensor 5 voltage circuits or the engine control module or ECM.

The voltage could be higher or lower than expected. The symptoms of a P code can vary, so it is important to get an understanding of the different issues you might face. It might include a hard or no start condition, the engine could start running rough, or you might notice that the vehicle no longer has the same fuel efficiency that it once did. The engine might misfire, and you would likely notice a lack of power in the vehicle.

However, in other cases, the engine light might be on.

The Onboard Diagnostics II standardized system is a computer system in many cars and trucks today that allows the vehicle to run self-diagnostics and reports. A mechanic will utilize an OBD-II scanner to diagnose the problem with your vehicle and access data regarding the fault and necessary repair. They will examine the data to determine when a code was set, reset the codes, and then test the vehicle to determine when the code returns, if it does. In many cases, the mechanic will be able to determine the problem based on the data they receive.

Determining that it is the P code and not one of the other trouble codes lets them know the next actions they need to take to help get the vehicle back in shape. The biggest mistakes when dealing with the P code diagnosis, or any diagnosis for that matter, is spending time looking at symptoms and stored codes that are present in the vehicle that might not have anything to do with the P code.

Naturally, this will lead to repairs that do not work. The P sensor code can be a big problem for your vehicle. While it might still be possible to drive the vehicle, at least for a time, the fuel efficiency may suffer.

As mentioned earlier, in some cases the vehicle will be more difficult to start, and it might not start up at all. Many times, the codes will not return, and you will not need to do any repairs to the vehicle.

However, if the code does come back and the issues with your vehicle continue or get worse, you will want to take it in for repair. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.

Religion, Politics and Cults in East Africa: God's Warriors and Mary's Saints.Analysis The former prime minister and chancellor presumably expected sterling to fall far more than it did after the vote, forcing the Bank of England to raise rates to attract money back to Britain.

But although the pound has fallen, the decline has not been calamitous (see below). As a result, the Bank was able to cut rates earlier this month. Those who want to take out fixed-rate loans have also seen rates fall. The price of these deals is driven by interest rates in the broader financial markets, such as yields on gilts (government bonds), which have fallen to new record lows. What has actually happened The pound has fallen and inflation is expected to rise, although the effects take time to work through the economy.

Analysis The fall in sterling predicted before the vote has come to pass, and inflation can be expected to follow in time. What has actually happened Theresa May has committed to keeping the triple lock for the rest of this parliament. Economic developments could render the triple lock unaffordable for the next government.

Baroness Altmann, who was pensions minister under Mr Cameron, has said the commitment to the 2. What has actually happened After an initial sharp fall, the stock market has rallied strongly to levels higher than those before the vote. Analysis Most workers other than fortunate members of final salary pension schemes have their retirement savings tied up in the stock market. Share prices therefore have a direct impact on the financial prospects of millions of Britons.

The London stock market did fall dramatically in the days after the Brexit vote, but has recovered strongly since. However, younger pension savers would arguably be better off with lower share prices, which would allow their regular contributions to buy more shares or fund units.

Their older counterparts will be more concerned with the value of their accumulated pots, which will broadly be higher in the wake of the vote.

First, some property funds were forced to suspend trading following a rush of investors who wanted to take out their money.

Many of these funds remain suspended. Second, final salary pension schemes have suffered from the further decline in gilt yields and interest rates. Their deficits, which are largely determined by gilt yields, have increased markedly since the vote. There has been speculation that embattled final salary schemes may have to be allowed to back down on some of their promises to ensure their viability, and to help keep their sponsoring companies afloat.

Have a question for our experts. Should I ask her to pay. Interest rates The prediction That rates would rise. Inflation The prediction Inflation will rise. Sterling The prediction The pound would fall sharply if Britain voted to leave the EU.

What has actually happened The pound has weakened, although less than expected. And what no one saw coming The Brexit vote also had some immediate consequences that few commentators seem to have predicted.
