Toyota Corolla Cleaning May Correct Faulty Mass Air Flow Sensor
The mass air flow sensor on higher mileage cars occasionally needs to be cleaned or replaced if sluggish acceleration is experienced or the Check Engine Light is illuminated with a mass air flow meter sensor fault code stored.
Engine has low power, and does not accelerate. Hesitates at times. Engine light is on. Sometimes engine stops running when slowing down or stopping on intersections. Sometimes it would run but RPM is steady at 1,000 to 2,000 RPM's and at 10-20 miles per hour speed, until you restart the engine and it would run normal again for sometime. 1. Cleaned MAF sensor: did not fix the problem 2. How to make sure that MAF sensor is faulty and need to be replaced? 3. Any recommendation? - vermakk

Looking for suggestions to resolve this problem. Cleaning MAF Sensor didn't fix it. How to make sure that MAF sensor is faulty and need a replacement? - Visitor
MY CHECK ENGINE DASHBOARD LIGHT CAME ON YESTERDAY. HAVE NOT EXPERIENCED ANY DIFFICULTIES THOUGH. PRAY THE light just goes out. At lease that I can pay for. :-). - Visitor
Sluggish acceleration while driving and starting in the morning. Removed and cleaned MAF and ran like new. - Visitor
Mass air flow sensor was bad. Lean condition bank1 code. replaced sensor. Happened again about 4 years later. - Visitor
Check engine light came on. Mechanic "found internal short of mass air flow sensor." Replaced. Car had been idling high and had increased gas consumption. - Visitor
The Check Engine light came on with MAS and Bank 1 too rich trouble codes being reported I cleaned the MAS with just canned air and the problem went away for three weeks before triggering the Check Engine light again. I am wondering if the OEM air filter that was installed about 3000 miles ago is defective and restricting the airflow so I just changed it out. I am also wondering if there may be some particles being released from the secondary charcoal air filter that may be collecting on the MAS wires that is causing a recurrance of the check engine light. I will be waiting to see if the light comes back on any time soon. - Visitor
hesitant acceleration and high RPM in 1st 2nd gear running rough until 3rd gear have tranny fluid changed on friday may clean or replace my MAS and hope it works - Visitor
Shortages water in the cooling system - Visitor
cooling fan keep run when i turn key on - Visitor
mass air flow had to be replaced -- check engine light was on - Visitor
bank 1 running to rich replaced 02 sensor and maf sensor still same problem rough idle terrible gas milege and engine shakes at certin speeds - Visitor
Ongoing problem that manifested itself during -30 to -40 degree days in winter now comes on in summer as well. Codes p0102, p0113 and p0171 have been observed. Cleaning MAF worked for a little while with CRC cleaner but codes keep coming back. Considering replacing MAF since wiring appears to be fine. - Visitor
I'm experiencing rough idle and sometimes sluggish acceleration. I have tried to clean the throttle body myself with cloth and a little petrol as I could not get a throttle body cleaner. Then I relearned it after that. But I'm not sure the problem is entirely fixed as it still is sluggish sometimes..and idles high attimes - Visitor
Cleaning the mass airflow sensor with MAF cleaner worked for a couple weeks and it improved pickup and reduced engine ping, but it returned a couple weeks later. - RickNY
same as vermakk! - April123
Replaving the MAF Sensor. - Visitor
new mass air flow sensor - Visitor
I haven't taken care of it yet, the cost they quoted me was $429.00. Too high. - Visitor
First clean 6 months later replace the sensor - Visitor
