    I have p 1121 and a P 0401 codes on my 1998 ford windstar. are these related? what can I check? replaced the mass airflow sensor recently.

    P1121 Ford Throttle Position Sensor Inconsistent with Mass Air Flow Sensor no they are not related !
    Are there any cracks in the rubber hose from air cleaner to throttle body ! That could cause the P1121 air entering after mass air flow sensor !
    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 55% or a TP V PID greater than 49.05% (2.44 volts) with a LOAD PID less than 30% indicates a hard fault. P0401 - EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on. The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum.
    • Vacuum supply
    • EGR valve stuck closed
    • EGR valve leaks vacuum
    • EGR flow path restricted
    • EGRVR circuit shorted to PWR
    • VREF open to D.P.F. EGR sensor
    • D.P.F. EGR sensor downstream hose off or plugged
    • EGRVR circuit open to PCM
    • VPWR open to EGRVR solenoid
    • D.P.F. EGR sensor hoses both off
    • D.P.F. EGR sensor hoses reversed
    • Damaged EGR orifice tube
    • Damaged EGRVR solenoid
    • Damaged PCM
    Perform KOER self-test and look for DTC P1408 as an indication of a hard fault. If P1408 is not present, look for contamination, restrictions, leaks, and intermittents

    Code P1102 - States pending fault.

    P1102 for the Mazda is :Mass Airflow Sensor Signal Inconsistent with Throttle Position Sensor. The Mass Airflow Sensor is located in the housing before the Throttle body; it reads the air coming into the system....the Throttle Position Sensor tell the ECU how much throttle you are asking for....I think that the in-air flow and the throttle are not getting the same answer; example would be that you are driving fifty miles an hour and either the MAS or the TPS are not seeing (receiving) this information. Note; most times the MAS is at fault, it can be cleaned but be very careful.

    I have a 2000 Lincoln LS 3.9L V8. Throwing codes for random misfires on different cylinders and a fault for TPS low input voltage. Is this due to bad COP's or could it be an ECM problem? Thanks!

    If it is several cylinders I would look at the mass airflow sensor. It can be cleaned with brake pad cleaner or mass airflow cleaner. Could also be a vacuum leak.

    Code 157

    Error code 157 on your vehicle indicates a problem with your mass airflow sensor. The mass airflow sensor gives a reading based on the air intake and output within the engine compartment. A properly functioning sensor will contribute to better fuel economy. In some instances, you may be able to clean your mass airflow sensor to clear the error code, but the error will most likely return in a short time. Fortunately, replacing the mass airflow sensor is a reasonably simple repair.

    Car is hesitating during acceleration

    Hi there i have a 2000 v6 camaro and i just rebulit the top end of the motor over the summer my car does this same exact thing ive diagnosed it as a tps but my throttle body is all one piece and i have fly by wire system so its about 500 to replace. when its really cold in the morning it doesnt like to idle smooth also because if my coolant temp. sensor. For you i would recommend doing a compression test on all of the cylinders, checking for spark, and also check and possibly replace tps( throttle position sensor)..

    yeah its pretty easy to change the mass air flow sensor. find the mass air flow sensor on your air intake an un screw it a n disconect the cable an replace. the tps...... if you are looking at the motor (standing in front of front bumber looking at the engine top right side of motor you will see the throttle sensor an all you have to do is un screw and put new one in. it should just fit right in with no problem.

    The mass airflow can get dirty and you will get trouble codes for everything under the hood except for the mass airflow. Try unplugging your mass airflow and driving the vehicle, if your problem goes away you need to clean the sensor. Buy some mass airflow cleaner though because other cleaners can damage the coating on the sensor.
