So now I have the temperature sensor cable ziptied up at the top of the pipe. The mass air flow (MAF) sensor samples and measures air going into the intake system, but blockage or contamination can skew sensor readings, leading to fuel trim problems. The first parameter is the engine speed, or revolutions per minute. This means with the key on engine off, you can push down gradually on the gas pedal and watch the throttle position voltage change in real time. Capture the movie or screen on the Scan Tool and return to the shop to enter the peak RPM and MAF values into the VE calculator along with intake air temperature, altitude, and engine displacement. Disconnect the MAF sensor. You can test a throttle position sensor with an automotive scan tool. Distance: Total cycling distance up to 99. It is easy to use these scan tool control buttons once you have tried it a few times. The factory provided a black, plastic, snap-on cover for the fuse box and a soft rubber boot for the diagnostic connector. Mass Airflow Sensor (MAF) – 1999-2006 5. Using a scanner and labscope. But even if you have a scan tool that has Mode $06 capability, it’s doubtful you would ever have the need to delve that far into the on-board diagnostics. Both a MAP sensor and MAF sensor for monitoring engine load and airflow. That's auto real-time HDR. Accessing DTCs must be done through the Data Link Connector (DLC), located under the LH side of the instrument panel, using a Suzuki (Tech-1) scan tool or an OBD II generic scan tool. Do not buy a MAF sensor unless the other tests indicate no problem. Check or replace all Oxygen Sensors if 80,000 miles or greater. Miata Bad MAF Sensor Diagnosis. Time: Total cycling time up to 99.

P0130 Closed Loop, Bank 1 Or Front O2S, Bank 1. The codes are also listed below. OBD diagnostic does not have to be difficult or inconclusive. so I thought. Note: Some MAF sensors also incorporate an air temperature sensor Inspect for any vacuum leaks downstream of the MAF sensor. 4 ounces, It is small best OBDII scan tool. When the crank sensor is replaced, it must be resynced to the PCM. This especially holds true for import European vehicles that demand a higher level Most of the MAF sensors in modern vehicles are equipped with a hot wire that calculates the volume of air. If using a scan tool, follow tool manufacturer’s instructions to clear Codes. Reads and Clears ABS/SRS Codes. 6 volts or above. This car does not have a map sensor but. Also, check that the port is free of carbon deposits or other debris, which could block the hose and lead to poor MAP sensor readings. To begin this DIY tutorial, we’ll begin by checking the Silverado MAP Sensor for power. Does the scan tool display DTC P0102 as active? Yes. Make it a habit to check your MAP sensor from time to time to maintain a sense of balance in your engine’s operation and ensure optimum performance for. To do the VE test, you have to make a WOT pull through a gear change whether it be the 1-2 or 2-3 and record certain data pids on the scan tool. When the PCM suspects there is an issue with the mass air flow sensor it will set a DTC code and illuminate the Check Engine light. The other test is with a scan tool. They make MAF sensor cleaner in a can. In a high gear (4th/5th), give full throttle from 2500 rpm up to 3500rpm. 225 grams per mile (gpm) of HC - which is almost nothing. MAF Sensor Tables.
