Code P0098 Ford is DTC code indicating issue with intake air temperature sensor 2 circuit. This sensor measures the temperature of the air entering the engine and provides the data to ECM. This data helps ECM adjust the air-fuel mixture and ignition timing for optimal engine performance and emission, when there is problem with the sensor’s circuit p0098 is triggered.
Possible Causes Code P0098 Ford
1.Faulty intake air temperature sensor 2 producing inaccurate reading or a consistently high voltage output.
2.Damaged, corroded or disconnected wiring or connectors between intake air temperature sensor 2 and ECM can lead to high input signal being sent to the ECM.
3.If intake air temperature sensor 2 is located too close to a heat source, such as exhaust manifold, it can lead to elevated temperature reading triggering p0098.
4.Faulty engine control module circuitry or software could cause it to interpret a high input signal from the intake air temperature sensor 2 even if the sensor is functioning correctly.
5.Any air leaks or restriction in the air intake system after the intake air temperature sensor 2 could potentially cause incorrect temperature reading.
6.Electronic interference from other components or system could disrupt the proper signal from intake air temperature sensor 2 to the engine control module.
7.Extreme weather condition such as very high or low temperature can affect the accuracy of intake air temperature sensor reading and trigger this code.
8.If intake air temperature sensor 2 has not been calibrated properly during installation. It might not provide accurate reading to engine control module and trigger this code.
Ford P0098 Possible Symptoms
1.Illumination of check engine light is most noticeable symptoms of p0098.
2.Engine might exhibit decreased power, acceleration and overall performance due to incorrect air-fuel mixture and ignition timing adjustment based on inaccurate temperature reading.
3.Faulty intake air temperature sensor 2 can lead to incorrect fuel calculation by the engine control module. Resulting in reduce fuel efficiency and possibly higher fuel consumption.
4.Engine might experience rough idling or even stalling when air-fuel mixture is not adjusted properly based on faulty temperature data.
5.In some cases malfunctioning intake air temperature sensor 2 can cause difficulty in starting the engine particularly in colder condition.
6.Incorrect air-fuel mixture adjustment can lead to increased emission due to incomplete combustion.
7.If engine control module receives incorrect temperature data, it might affect transmission’s shifting point causing irregular or harsh shifts.
8.If intake air temperature sensor 2 is delivering inaccurate data during cold starts, engine may struggle to operate efficiently during this phase.
9.Inaccurate temperature data can reduce turbocharger performance and boost level in turbocharged engines.
How To Fix P0098 Ford
1.Inspect wiring, connector and harness for any signs of damage, corrosion or loose connection associated with the intake air temperature sensor 2.
2.Test the intake air temperature sensor 2 using multi-meter. Compare resistance or voltage reading to the specification provided in the vehicle manual. If reading are out of range replace the sensor.
3.Ensure that the intake air temperature sensor is properly positioned and not exposed to excessive heat source. Incorrect sensor positioning can lead to inaccurate temperature readings.
4.Repair or replace damaged or corroded wires and ensure proper insulation and routing to prevent future problem.
5.If intake air temperature sensor 2 is found to be faulty or out of range replace the sensor with a new one.
6.After repair are completed use OBD II scanner to clean the DTC code and reset the check engine light.
Its important to have the vehicle inspected and diagnosed by professional mechanic to find and resolve issue related with Ford p0098 for proper repair.
