Common causes of Fairthorpe Mk P1093 include four-wheel drive switch or actuator failures. Other causes include faulty sensors, solenoids, or switches, and defective wiring harnesses and connectors.
Common Symptoms For Fairthorpe Mk P1093
The PCM recognizes these voltage variations as exhaust gas temperature and it reacts accordingly, adjusting ignition timing or the air/fuel ratio in order to lower the exhaust gas temperature and protect the catalytic converter. When the PCM demands the reductant injector "ON" it begins to monitor the upstream and downstream exhaust gas temperature, exhaust gas pressure, or heated oxygen sensor/s to determine if there is sufficient reduction temperature, pressure, or noxious gas levels
Repair or replace any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful
A scanner (or code reader) and a digital volt/ohmmeter will be required to successfully diagnose this code. Virtually every vehicle (with an automatic transmission) produced since the mid-eighties is equipped with some type of computer controlled automatic transmission system
If either the reference voltage or ground circuits are open, use the digital volt/ohmmeter to check for continuity (disconnect all related control modules from the circuit before checking circuit resistance or controller damage may occur) and resistance in all circuits
Accelerator Pedal Position (APP) Sensor 1 Performance
BBV Sensor Circuit Low Voltage
A/C System High Pressure High Temperature
Fairthorpe Mk P1093 Troubleshooting
A sure sign of this is smoke or steam being emitted from underneath the hood. The ignition timing could be set incorrectly and will require adjustment. If, when looking under the hood, you notice that the drive belts appear loose, they need to be tightened or completely replaced. If there is a noticeable pool of fluid underneath the car, this could be a sign of the cylinder head gasket failing. That will be confirmed in the form of billowing smoke being blown from the exhaust system. Fairthorpe Mk P1093 OBD2 may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
How to turn off Fairthorpe Mk P1093 check engine light ?
There are two ways to turn off the check engine light:
A repair technician can do so once repairs have been made.
The OBD II can automatically turn it off when it fails to detect the problem after several diagnostic cycles.
