Re: Torsion Resonant Frequency (TPMS)

Hello, Due to the elastic properties of a tire, while driving, the rim speed v1 will be different from the speed of the outer part of the tire v2. The magnitude of the difference is determined (among others) by a torque constant k which is proportional to the tire pressure.While driving, the irregul...

Re: WPS500X Using with snapon Compression adapters??

Hello, Please add some codes for your adapters,I think you need a Foster series 2 female to rectus 21 (or 26) female adapter.You can build one with these parts: https://www.ebay.com/itm/Rectus-21-Typ-Kupplung-Wassereinspeisung-Bsp-Buchse-Fassung-Mikrobore-21-Schnell-/115375250888?var=&hash=item1adce...

Re: What is the correct way to test the fuel low pressure system on a Skoda Octavia 1.6 TDI - CHLA engine type?

Hello, According to the Bernoulli's equation the sum of the static pressure and dynamic pressure will be constant:if the WPS 500 adapter introduces a restriction, the static pressure will be a lower one,in some cases even negative.Also the value -1.5 Bar is a nonsense,you can't have a value lower th...

Re: Toyota oxygen sensor not showing right?

Hello, From air/fuel sensor you can measure -0.36 mA current at air -fuel ratio 13 ,0 mA at fuel-air ratio 14.7, ,0.36 mA at fuel-air ratio 17.7.This current is pumped by ECU in sensor circuit to keep voltage at 0.4 v between AF+ and AF-,better use a scan tool to read air/fuel ratio,even with K2 cla...

Re: Curious secondary "mega"-spike!!

Hello,
Maybe a good connetion to ground will help ,sometimes the capacitive/inductive probes need it.

Re: WPS500X dodgy readings?

Hello, Please use the info from post https://www.picoauto.com/support/topic16131.html?&p=64421&hilit=stc#p64421 about how to use the readed values:the internal volume of sensor is 1.2ml,the hose will add 2 ml ,also you must measure the volume of glow plug adapter (using engine oil and a 5ml syringe,...

Re: Misdiagnosis

Hello,
I think you must report this wrong description of fault codes,in ESI Ticket/Diagnosis,maybe you can add TSB with fault description as an attachment.

Re: Toyota Auris

Hello, Your engine was disassembled?Why do you suspect the timing chain?Some parts was replaced? If you can't find some good signals from CAM-CRANK you must check the fuel rail pressure,also the compression and injection (the main injection is at TDC at starting or a few degrees earlier). If you do...
