P0115 Injin Coolant Yanayin Sensor Circuit Malfunction

Lambar matsala P0115 OBD-II Takardar bayanai

Sensor Coolant Sensor (ECT) Matsalolin kewayawa

Mene ne wannan yake nufi?

Ana ganin wannan Lambar Matsalar Bincike (DTC) gaba ɗaya kamar yadda ta shafi duk motocin da aka sanye su da OBD-II na 1996. Takamaiman matsala da matakan gyara na iya bambanta kaɗan dangane da alama / ƙirar.

ECT (Injin Coolant Temperature) firikwensin thermistor ne wanda juriyarsa ke canzawa da zafin jiki. Yawanci wannan shine firikwensin waya 5, siginar nuni na 0115V daga PCM (Module Control Module) da siginar ƙasa zuwa PCM. Wannan ya bambanta da SENSOR TEMPERATURE (wanda a koyaushe yana sarrafa firikwensin zafin gaban allo kuma yana aiki iri ɗaya da SENSOR, kawai shine kewaya daban fiye da wanda PXNUMX ya shafi).

Lokacin da zazzabi mai sanyaya ya canza, juriya na ƙasa yana canzawa a PCM. Lokacin da injin yayi sanyi, juriya tana da girma. Lokacin da injin ya yi ɗumi, juriya ba ta da ƙarfi. Idan PCM ya gano yanayin ƙarfin lantarki wanda ya bayyana yana da ƙarancin ƙima ko babba, P0115 shigar.

Alamomin kuskure P0115

Alamomin lambar matsala P0115 na iya haɗawa da:

• ECM yana kunna hasken Injin Duba kuma yana shiga yanayin rashin tsaro, yana watsi da shigarwar a 176 Fahrenheit.
• Maiyuwa injin ba zai iya farawa da kyau lokacin sanyi ba kuma yana farawa kamar yadda aka saba lokacin dumi.
• Injin na iya yin aiki da ƙarfi kuma yana jujjuyawa har sai injin ɗin ya yi zafi
• Ya kamata injin ya yi aiki kusa da al'ada da zarar injin ya ɗumama.
• MIL (Lamp Indicator Lamp) A Koyaushe
• Motar na iya zama da wahalar farawa
• Zai iya busa hayakin hayaƙi mai yawa kuma ya zama mai arziki sosai
• Injin na iya tsayawa ko bututun da ke fitar da hayaki na iya kamawa da wuta.
• Ana iya sarrafa injin akan cakuda mai ɗorawa kuma ana iya lura da ƙimar NOx mafi girma (ana buƙatar mai binciken gas)
• Magoya bayan sanyaya za su iya ci gaba da gudana lokacin da bai kamata su yi gudu ba, ko ba lokacin da ya kamata su yi gudu kwata -kwata.

Kewayon firikwensin ECT da aka yi amfani da shi ga ECM ya tashi zuwa -40°F ko sama da 284°F, yana nuna gajeriyar kewayawa ko buɗaɗɗe.

Lambobin P0117 ko P0118 na gajere ko buɗaɗɗen kewayawa yawanci suna rakiyar lambar P0115.

Yawancin lokaci ana iya danganta dalilin da kuskuren firikwensin ECT, amma, wannan baya warewa masu zuwa:

• An lalata wayoyi ko mai haɗawa akan firikwensin
• Buɗe ko gajeriyar da'ira a cikin nuni ko kewaye sigina
• Buɗewa ko gajere kewaye a cikin siginar siginar
• PCM mara kyau

Na farko, duba na'urar firikwensin don lalacewar wayoyi ko mai haɗawa da gyara idan ya cancanta. Bayan haka, idan kuna da damar yin amfani da na'urar daukar hotan takardu, tantance abin da zafin zafin injin yake. (Idan ba ku da damar yin amfani da kayan aikin sikan, yin amfani da firikwensin zafin jiki a kan dashboard na iya zama hanya mara tasiri don gano zafin zafin. Wannan saboda lambar P0115 tana nufin SENSOR ECT kuma dashboard ɗin yana sarrafawa, yawanci waya SENDER guda ɗaya. Ainihin shine wani firikwensin wanda lambar bata amfani dashi.)

2. Idan zafin injin ya yi yawa, kimanin digiri 280. F, wannan ba al'ada bane. Cire haɗin firikwensin akan injin kuma duba idan siginar ta faɗi, faɗi, debe digiri 50. F. Idan haka ne, zaku iya cin amanar firikwensin kuskure ne, gajarta a ciki, yana haifar da aika siginar ƙaramin ƙarfi zuwa PCM. Koyaya, idan kuna son tabbatar da cewa wannan firikwensin ne ba wayoyi ba, zaku iya yin wasu gwaje -gwaje. Tare da naurar firikwensin ECT, tabbatar cewa kuna da 5 volts a cikin kewayon tunani tare da KOEO (maɓallin kashe injin). Hakanan zaka iya duba juriya na firikwensin zuwa ƙasa tare da ohmmeter. Tsayayyar firikwensin al'ada zuwa ƙasa zai ɗan bambanta kaɗan dangane da abin hawa, amma galibi idan zafin injin yana kusan digiri 200. F., juriya zai kasance kusan 200 ohms. Idan zazzabi yana kusa da 0 def. F., juriya zai wuce 10,000 ohms. Tare da wannan gwajin, zaku iya tantance idan juriya na firikwensin yayi daidai da zafin injin. Idan bai dace da zafin zafin injin ku ba, to wataƙila kuna da firikwensin firikwensin.

3. Yanzu, idan zafin zafin injin bisa ga na'urar daukar hotan takardu ya kai digiri 280. F. da cire haɗin firikwensin baya haifar da faduwa a cikin karatun zuwa digiri 50 mara kyau. F. An gajarta shi a wani wuri kai tsaye zuwa ƙasa.

4. Idan karatun zafin zafin injin a kan na'urar daukar hotan takardu ya nuna mummunan digiri 50. Wani abu kamar wannan (kuma ba ku zaune a cikin Arctic!) Cire haɗin firikwensin kuma duba don ƙarfin lantarki na 5V akan firikwensin.

5. In ba haka ba, duba mahaɗin PCM don dacewa 5V mai dacewa.Idan akwai a kan haɗin PCM, gyara madaidaiciya ko gajeren da'irar a cikin bayanin 5V daga PCM. Idan mai haɗin PCM ba shi da bayanin 5V, to kun kammala ganewar asali kuma PCM na iya yin kuskure. 6. Idan da'irar nuni na 5V ba ta cika, gwada siginar ƙasa a PCM ta amfani da gwajin juriya na ƙasa da ya gabata. Idan juriya ba ta dace da zafin zafin injin ba, rage juriya na siginar ƙasa zuwa PCM ta hanyar cire haɗin siginar ƙasa daga mai haɗa PCM. Wayar dole ne ta kasance babu juriya, an cire ta daga PCM zuwa firikwensin. Idan haka ne, gyara rata a siginar zuwa PCM. Idan ba shi da juriya a kan siginar ƙasa siginar kuma gwajin juriya na firikwensin al'ada ne, to ku zargi PCM mara kyau.
