Tp_r Obd2
What's the difference between OTBT scanner throttle TP_R, TP_B, app_D, app_E, TAC_PCT and TP? 3
I am looking for clear information about OBD scanner data. Where can I review this sensor and the logic behind its operation? I've combed through the internet, FO, library and my SP manual, but they all talk about bugs, not patterns.
EGR is ordered to be 0%, but indicating that its position is 99.2%, does not seem correct. What is the logic behind how these elements work? How EGR works at specific temperature and vacuum etc.
updateGlad to hear from someone who understands. Thank you very much. The difference between the entries is not yet clear to me, as they are formed from each other based on elements that I do not know.
The displays are in percent and the OBD data are unreadable to each other. TP (%), TP_R (%), TP_B (%), APP_D (%), APP_E (%), TAC_PCT (%) are all low and increase as much as you pedal. TP (%) was the only person who followed the diet.
APP_D (%), APP_E (%) almost follow the pedal. And APP_E (%) is 42% while APP_D (%) is 85% on pedals. TP_R (%) and TP_B (%) are mostly the same, but 18% behind TAC_PCT (%).
Active: TP (%) = 18%, TP_R (%) = 8.6%, TP_B (%) = 34.1%, APP_D (%) = 20%, APP_E (%) = 9.4%, TAC_PCT (%) = 9%.
EGR is shown as a percentage. Normally rotates 45% less than idle or full throttle as you say with +/- 8% error, but when EGR control is at 0% idle and full throttle it shows 99.2% error, which makes me Surprisingly, no. Don't feel
It operates the speed system electronically.
Unlike the real butterfly valve, the position of the butterfly valve (TP) is completely open or closed. The TP sensor has 2 identical sensors for redundancy / backup and they are read opposite to each other. TP_R is only sensor 1 and TP_B is sensor 2. It can also be A and B.
Most use a maximum of 5 volt reference voltage. In this case, the sensor is just a rheostat.
So ... with the butterfly valve closed, TP_R will display approximately 5 volts as 4.8 volts, 0.2 volts at the lower end of the voltage scale and TP_B at the upper end.
When the throttle is open and then fully open, the TP_R sensor voltage will be read to 4.8, while the TP_B-SS value will be reached to 0.2. ..... like a mountain range from the sea! In the central region, this is the only occasion when two sensors read the same thing at 2.5 volts, one up and one down, in the middle.
This is exactly how the accelerator pedal position sensor (APP) works! This app measures how much the driver presses the accelerator pedal.
With Key On, January Off ... you can gently step on the accelerator pedal and see how the two APP sensors move. Throttle doesn't usually move when the power goes off, but it can happen! However, you can choose to close immediately after not seeing any RPM for a certain period of time. Therefore, even when the engine is running, do not try to manually open the throttle lever by turning on the key. You can actually close and remove your fingers.
To confirm or clear the proper operation to open the throttle manually or manually, the key must be removed completely. Or better yet, just pull the gas.
In addition, the throttle has a built-in spring to keep it 15% open in case of sensor / power malfunction, so that you can easily get the car off the road.
In terms of EGR ... 0% means off. 100% means completely open. Basically 2 times it will be at 0%.
1. Raise or slow down your legs.
2. At full speed.
The EGR works best between closed and fully open throttle, i.e. B. When driving on medium throttle. For example, keep the road at 40 miles per hour as you would on a cruise ship.
Sometimes, in some cars and scanners, some information gets confused because of the software. Your 99.2% EGR should mean that you are still open. However, you can try to say that it is 00.8% which is still 0% and is closed.
Significantly slower, the EGR can open up 99.2%. If it works fine, I'll run it and see if the% acceleration light goes to 40. If so, it's in the scanner's programming and vice versa.
Of course, it can only be returned with 1 pid.
