Multimeter Tester: Although generic, the specific repair steps may vary depending on make/model. A P0222 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V). The B refers to a particular circuit, sensor, or area of a particular circuit. Code P2138 is an accelerator pedal position (APP) sensor or throttle position (TP) sensor code. In simpler terms, it’s an OBD-II code triggered when one of the two sensors in your gas pedal malfunctions. As our mechanic explains in the video above (1:07), a gas pedal has two APP sensors to essentially serve as fail-safes for each other in Diagnostic trouble code (DTC) P2074 stands for “Manifold Absolute Pressure/Mass Air Flow–Throttle Position Correlation at Higher Load.” The P2074 code registers when the powertrain control module (PCM) detects signals from the manifold air pressure (MAP) or mass airflow (MAF) sensor that don’t meet the expected values. Here is the full procedure for testing the H.O (91-01) throttle position sensor. -----The throttle position sensor is connected to the throttle shaft on the throttle body. It sends throttle valve angle information to the PCM. The PCM uses this information to determine how much fuel the engine needs. The Top 3 Symptoms of a Bad Cam Position Sensor. Do you think you might be dealing with a bad CMP sensor? If your vehicle is exhibiting one or more of the following symptoms, you might be correct. Note: Because other problems can present the same symptoms as a faulty CMP sensor, you’ll want to perform a thorough diagnosis before condemning It was a missing, yes missing, elbow on the vacuum line from the PCV to the manifold way in the back behind the throttle body. 2004 Jeep Grand Cherokee WJ Overland, 4.7V8 HO 125K miles. Symptoms: sudden onset of high idle (NOT rough idle) on startup (1000 rpm) and at warmup idle jumps to 1200-1500 depending on A/C on/off, drive or park/neutral. TEST 1: Testing The TPS Voltage Signal. TEST 2: Verifying TPS Has Power. TEST 3: Verifying TPS Has Ground. More Jeep 4.0L Test Tutorials.
