So you should chech it on our car models. P if your catalytic convertor fails completely, you eventually won't be able to keep the car running. Your gas mileage will also be terrible, so you should try and fix it as soon as you can.

Is the fuel pump sometimes not priming when you turn the key to ON II? Start by measuring the fuel pressure and checking whether you have bright white-bluish spark at all four plugs. The mechanical timing is also something that you should check, as we mentioned above. P DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments.

Will it say not present as the light was not on when testing? I broke down a couple of years ago, loss of power.

I re soldered dry joint on ECU. Would this have kicked up some codes? Any guidance would lorawan weather station much appreciated.

Bit worried about the critical malfunction. Don't really notice any thing when driving. Been a couple of garages who were crap. Rather look in to it myself now Many thanks. All generic codes, these and as such not overly helpful.

Personally I'd clear the codes and see if they return, and then see about how to clean the EGR valve. Burnerman19 Jan Ok, What about the black smoke? What could that be.

I mean it's thick black. Again, pretty common when the EGR valve is coked up These things allow some exhaust gas to be burnt twice to lower combustion temperature and help reduce emissions I have to say they do work but they always give bother after a few miles. I am a gas engineer so am pretty handy.We recommend Torque Pro. This article will therefore deal with code P as it applies specifically to GM vehicles. On many GM products, the throttle control mechanism is of the drive-by-wire type, which means that there is no physical connection such as a control cable between the throttle pedal and the throttle body.

The changing voltage is interpreted by the PCM as changes in the position of the throttle pedal, and depending on the resulting change in the reference voltage, the PCM will rotate the throttle plate to a position that corresponds to the position of the throttle pedal. For example, if the throttle pedal is in the rest position, the throttle plate will be in the closed position.

Conversely, if the throttle pedal is in the fully depressed position, the throttle plate will be in the WOT Wide Open Throttle position. In the real world, however, the throttle pedal assembly contains up to three sensors, with only one sensor that is directly involved with controlling the position of the throttle plate. The other sensors serve to monitor a the movement of the throttle pedal, and bthe correlation between the primary throttle pedal position sensor and the throttle plate.

Thus, as a vehicle ages, the combined, and cumulative effects of excessive mechanical components of the throttle control system can cause miscorrelations between the positions of the throttle pedal and the throttle plate. While drive-by-wire throttle control systems have some capacity to compensate for mechanical wear of parts, this ability is limited, and easily overcome when several mechanical components wear out at different rates. It should be noted though that while the definition of this code refers to throttle pedal position sensor faults, which suggests failures, defects, or malfunctions in one or more sensors, as opposed to miscorrelations between sensors, the fact is that failures, defects, or malfunctions in these sensors are primarily caused by excessive mechanical wear of sensor parts.

Therefore, while miscorrelations typically occur as the result of worn-out parts, OBD II systems cannot identify the actual parts that may be worn out, which explains why this code does not specifically refer to sensor miscorrelations, but to failures, defects, or malfunctions, that cause miscorrelations. This is of course not the same as saying that mechanical wear is the only possible cause of code P on all GM products, but is the primary cause of this code on older or high-mileage GM applications.

For more information on other possible causes, see the Common Causes section. Nonetheless, when the PCM detects any failure or malfunction in any sensor in the throttle pedal position sensor, it will recognize that it cannot control the throttle effectively, and it will set code P, and illuminate a warning light as a result.

This image shows the throttle pedal position sensor on a Chevy Malibu. While the actual appearance of the throttle pedal position sensor on other GM applications differs from this example, the actual pedal position sensor will always be located on, or be attached to the throttle pedal. Thus, in some cases, it may be possible to replace only the actual sensor, while in other cases the throttle pedal must be replaced as a complete assembly.

NOTE 1: Be aware that diagnosing this code on GM applications typically requires the use of GM-specific diagnostic equipment, although it might be possible to extract some additional fault codes with a high-end scan tool.

Since there are several sensors involved in throttle control, a dealer-grade scan tool with bi-directional controls is required to perform the 18 steps that must be completed in the correct order to make a definitive diagnosis. In nine out of every instances of this code, replacing the complete pedal assembly will resolve the issue definitively.

Why is the Engine Light ON? Repair Importance Level: 3.On an initial test drive the car was indeed slightly low on power. We performed a fault code read but no faults were present. So the next step was to check the turbo boost pressure on live data with the Tecnomotor socio The first check was to check the boost reading with the key on but engine off and it was reading mbar, this proved the sensor was at the correct starting point.

Then the maximum boost pressure reading was checked when we were driving at full load and the max it was going to was mbar or 0. And the desired boost reading the socio was showing was mbar so we were 0. The 1 st thing we noticed was that this engine had a waste gate controlled turbo and not the more popular variable geometry turbo. And most waste gate controlled turbos normally had a small boost pressure pipe connected to the waste gate actuator which when the boost reached the maximum desired pressure the boost pressure would overcome the spring pressure in the actuator and open the waste gate and reduce the boost pressure.

But on the vehicle it did not work on boost pressure to open the waste gate instead it was controlled by vacuum, So It had a boost control solenoid and when full boost was required there was no vacuum sent to the actuator and the waste gate was closed and when the boost reached the maximum allowed the ECU would then operate the boost control solenoid and send a vacuum to the actuator and reduce the boost.

So now to see why the boost was low The 1 st thing we normally do in these cases is to check for boost leaks with a smoke machine filling the complete intake system with smoke and then looking for a leak, but there were no leaks visible externally and by viewing the flow meter on the smoke machine see fig. So we decided the next step was to check the actual boost pressure with our Digital turbo pressure tester. As there is nowhere to T into the turbo system on this car this tester is very useful as it works by inserting a small needle into the rubber turbo pipe.

The needle is inserted in the direction of air flow fig 2 through the pipe so that after the needle is removed the turbo pressure closes the hole that the needle made therefore eliminating any risk of causing a leak by the needle.

When this test was performed we found that we were getting over 0. Fig 2. Fig 3. So we knew from this that the system was developing much more boost than the reading that we were getting on our diagnostic tool.

The next step was to remove the turbo boost pressure sensor which on inspection fig 3 was badly blocked with carbon as was the intake manifold. On cleaning the manifold and replacing the boost pressure sensor the full power was restored to the car. As 9 times out of 10 you will be saving the customer money but charging more time for diagnosing it fully and changing less parts. Written by: Ryan's Automotive.Check the following items.
