2. Nemo wurin firikwensin firikwensin ƙasa 

Gano wuri mai maƙarƙashiya yana ƙayyade idan akwai matsala kuma yana taimakawa tare da bincike na gaba.

Saita multimeter zuwa kewayon ƙarfin lantarki 20 VDC, kunna wuta ba tare da kunna injin ba, sannan sanya ja-jarin gwajin gwaji akan madaidaicin matsayi na baturin mota (alama "+"). 

Yanzu sanya jagorar gwaji mara kyau na baƙar fata akan kowane jagorar waya ta TPS ko tashoshi.

Kuna yin haka har sai wanda ya nuna muku karatun 12 volts. Wannan tashar tashar ku ce kuma TPS ɗin ku ta ci wannan gwajin. 

Idan babu ɗayan shafukan da ke nuna karatun 12-volt, to, TPS ɗinku ba ta da tushe sosai kuma yana iya buƙatar gyara ko maye gurbin gaba ɗaya.

Idan ƙasa ta kasance, duba shafin ƙasa kuma ci gaba zuwa mataki na gaba.

3. Nemo wurin ma'aunin wutar lantarki

4. Duba ƙarfin siginar TPS 

Gwajin ƙarfin lantarki na sigina shine gwajin ƙarshe wanda ke tantance idan firikwensin matsayi na maƙura yana aiki da kyau.

Wannan yana taimakawa tantancewa idan TPS tana karanta ma'aunin daidai lokacin da ya buɗe cikakke, rabin buɗe, ko rufe.

Saita multimeter zuwa kewayon ƙarfin lantarki na 10 VDC, sanya jagorar gwajin baƙar fata a kan tashar ƙasa ta TPS da ja-gorar gwajin ja akan tashar wutar lantarki ta sigina.

Yana iya zama da wahala a sanya jagorar multimeter akan tashoshi tun lokacin da aka riga an haɗa TPS zuwa maƙura.

A wannan yanayin, kuna amfani da fil don juyawa-bincike wayoyi (huda kowace waya TPS tare da fil) kuma ku haɗa multimeter yana kaiwa ga waɗannan fil (zai fi dacewa tare da shirye-shiryen alligator).

A faɗin maƙura, multimeter ya kamata ya karanta tsakanin 0.2 zuwa 1.5 volts idan firikwensin matsayi na ma'aunin yana cikin yanayi mai kyau.

Ƙimar da aka nuna ta dogara da samfurin TPS ɗin ku.

Idan multimeter ya karanta sifili (0), har yanzu kuna iya ci gaba zuwa matakai na gaba.

Sannu a hankali buɗe maƙura kuma kalli canjin karatun multimeter.

Ana sa ran multimeter ɗin ku zai nuna ƙima mai ƙaruwa koyaushe yayin da kuke buɗe maƙura. 

Lokacin da farantin ya cika buɗewa, multimeter shima yakamata ya nuna 5 volts (ko 3.5 volts akan wasu samfuran TPS). 

TPS yana cikin mummunan yanayi kuma yana buƙatar maye gurbinsa a cikin waɗannan lokuta:
