Hey Scotty, we have a 2007 Mercury Montego AWD automatic with 112,000 miles on it. Replaced the air filter the other day & now we're having a series of problems. Not sure if the problems are related. First, the gas pedal would not go down & it threw up a check engine light & a code for a misfire on cylinder 6 & MAF sensor. We replaced the MFA & the cylinder 6 coil. Cleared the codes. Then today, the check engine light came on again & the car went into limp safe mode. Checked the codes again & it's now showing 2 other different codes...P2195 & P061B. I've read about throttle body issues, throttle sensors, accelerator pedal sensors, o2 sensors, etc. Do you have any idea what is going on with this thing? I don't want to be chasing all of these issues & still not fixing the problem. Any advice would be appreciated. Thanks!
The P2195 code is a result of the engine control module (ECM) indicating that the oxygen sensor is fluctuating outside its optimal range. This code indicates that the engine could be running lean or that there is a fault in the A/F O2 sensor.
When a code P061B is stored, it means that the powertrain control module (PCM) has detected an internal performance error in the engine torque monitoring system. Other controllers may also detect an internal PCM performance error (with the engine torque monitoring system) and contribute to a P061B being stored.
