Power Directed through oil pressure switch to fuel pump. Possible bad oil pressure switch.
Low voltage (high vacuum) at mass air flow sensor (or MAP sensor).
there is no map sensor on it
the exhaust, where every o2 sensor is
3.1L dont have a crank sensor
Throttle position or pedal position sensor/switch circuit, low input
You can find the 1995 Pontiac Firebird 3.4 liter engine IAT sensor on the back of your engine. The IAT sensor will be a few inches above the transmission.
replace the sensor.
Map sensor circuit voltage highMap sensor circuit voltage high
on the transmission tailshaft housing
If it has fuel injection it has one
When it says the map sensor voltage is too high, this means that too much voltage is reaching the sensor. This can be a result of a failed component or a shorted wire coming into the sensor.
Bank 1 Sensor 2 is the sensor AFTER the catalytic converter. Causes could be,A faulty O2 sensor, Exhaust leak near the sensor, Damaged catalytic converter, Damaged wiring to O2 sensor,
