If you're driving a pre-1995 vehicle with OBD I, the check engine light is lit by the MAP
sensor diagnostic trouble code: 33 (Manifold Absolute Pressure Sensor Circuit High Signal) or 34 (Manifold Absolute Pressure Sensor Circuit Low Signal).
Not exact matches
When the manifold absolute pressure (MAP)
sensor fails, the check engine light will turn on and you'll see one of the following
diagnostic trouble codes:
Hi - the
diagnostic trouble codes you mention are: 33 - Manifold Absolute Pressure circuit /
sensor malfunction: wiring open circuit / shorted circuit to positive, hose blocked / leaking, MAP
sensor, 34 - manifold Absolute Pressure circuit /
sensor malfunction: wiring shorted to ground, 42 - ignition control module circuit...
The P0500
diagnostic trouble code tells us there is a fault found with the vehicle speed
sensor.
Features: With the appropriate applications, perform the following operations: Read
diagnostic trouble codes, both generic and manufacturer - specific, and display
code descriptions with over 3000 universal
code definitions in the database Clear
diagnostic trouble codes and turn off check engine lights Display and record real - time
sensor data, including: · Vehicle Speed · RPM · Fuel Consumption · Engine Coolant Temp · Fuel Pressure · Calculated Engine Load · Throttle Position · Intake Manifold Pressure · Air Intake Temp · Timing Advance · Mass Air Flow · Fuel Level · Barometric Pressure · EVAP System Vapor Pressure · Fuel Trim · + More Note: Your vehicle may not support all engine metrics.
The most common causes of
Diagnostic Trouble Code P2118 are failure of the throttle actuator control motor, a failed pedal position
sensor, a faulty throttle position
sensor, an open or short in the actuator circuit, or a poor electrical connection anywhere in the control circuits for the foregoing components.
If the voltage signal reading of the manifold absolute pressure (MAP)
sensor sends a voltage signal to the PCM that does not coincide with the voltage signal that is sent from the MAF
sensor, the P2281
diagnostic trouble code will be stored and the check engine light will come on.
If
diagnostic trouble code P0101 (https://www.yourmechanic.com/article/-p0101-obd-ii-
trouble-
code-mass-airflow-maf-circuit-operating-range-or-performance-problem-by-john-nelson) has been stored, that means that the Mass Airflow (MAF)
sensor is sending signals that are out of the normal range.

The P2403
diagnostic trouble code (DTC) is an indication that the evaporative emission (EVAP) control system leak detection pump
sensor has an open circuit.
The potential causes of
Diagnostic Trouble Code P0420 include a damaged muffler or leaks in the muffler, damaged exhaust manifold or leaks in the exhaust manifold, damaged exhaust pipe or exhaust pipe leaks, misfiring in the engine, oil contamination in catalytic converter, a faulty catalytic converter, a faulty engine coolant temperature
sensor, faulty front oxygen
sensor, faulty rear oxygen
sensor, damaged oxygen
sensor wiring, oxygen
sensor wiring that is not properly connected, damaged oxygen
sensor connectors, a fuel injector that is leaking, fuel pressure that is high, and other causes.
