家泯, 小葉,
今天換完節氣門後, 故障碼過一陣子又跑出來了, 花了點時間爬了一下文, 找到下面的說明, 就是有超過下述標準時, 故障碼會出現.
不過有些 "關鍵字" 看不懂, 上來請教一下, TP PID 是不是就是TP 電壓? LOAD PID 是什麼呢?
我們要不要找個時間試試看ST220 的集器箱呢?
下面是另外一個網站的說明:
P1121 – Throttle Position (TP) Sensor Inconsistent with MAF Sensor
The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If during key ON engine running self-test the comparison of the TP sensor and MAF sensor readings are not consistent with calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
* Air leak between MAF sensor and throttle body
* TP sensor not seated properly.
* Damaged TP sensor
* Damaged MAF sensor
Drive vehicle and exercise throttle and TP sensor in all gears. A TP PID (TP V PID) less than 4.82 % (0.24 volt) with a LOAD PID greater than greater than 49.05% (2.44 volts) with a LOAD PID less than 30% indicates a hard fault.
