My Suzuki jimny stoped whiledriving


many suzuki have 2 baros, mine has 3.

one for altitude, inside ecu,

one for map TBI engine, (map sensor main 108 fails )

one for EGR map, to test EGR only. (my G16b has it)

we dont have 1.3 Jimny's here so can look it up for you.

but the FSM for your car (book) has this.

the P0108

is the main engine map sensor. (using usa fed rules for OBD2)

yours is EOBD rules. (im clueless with those)

that is used to calculate all air flow through the engine

it's output is stuck high,,

it's unplugged is my guess.

our map does 3.9V with the vacuum hose pulled. or just key on.



over 3.9v is illegal voltage and is bad map or unplugged.

when it goes to near 0v.volts at full vacuum 29"



this page may match your map for all voltages and states.

that is my best idea here , lacking non USA books,

I have a 98 safari van that has been put on a scanner which the codes read: P0420(catalyst system efficiency below threshold-bank1), P0452(evaporative emission control system pressure sensor low imput) and...


You may need a mechanic. At least a shop manual.
The catalytic converter code means the computer does not think the cat is working right based on input from the O2 sensors. That data would need to be checked out and verified along with a temp scan of the cat itself.
The other two codes are saying the signal from the pressure sensor is too high and too low. The computer measures pressure inside the gas tank to make sure it vents correctly. The pressure sensor could be faulty, or it could be something else in the venting system.

Once the enigire is started it over revs itself without imputs from the accelerator pedal. I have tried replacing the MAP sensor but it made no change.


The ones to look at is the tps sensor( throttle position ) and the isc( idle speed control) if the isc motor is stuck open or shorted it will cause this.Make sure throttle cable isn't bound up.

Component locator - cannot find the MAP sensor


TESTING-MAP- A vacuum line runs from the sensor mounted high to the intake manifold so it can measure the vacuum in the intake manifold. NOTE: Unusually high or low barometric pressures can generate a false DTC for the MAP sensor. If no driveability symptoms accompany the MAP code, do not replace it.
  1. Connect a MAP/BARO tester to the sensor connector and sensor harness connector. With ignition ON and engine OFF, use DVOM to measure voltage across tester terminals. If the tester's 4-6V indicator is ON, the reference voltage input to the sensor is okay. NOTE: The green light on the tester indicates that the VREF circuit is okay, 4-6 volts. A red light or no light indicates the VREF is either too low or too high.
  2. Measure the reference signal of the MAP sensor. If the DVOM voltage reading is as indicated in the table, the sensor is okay.
    1. Turn the ignition OFF.
    2. Disconnect the vacuum hose from the MAP sensor and connect a vacuum pump in its place.
    3. Apply 18 in. Hg of vacuum to the MAP sensor.
    4. If the MAP sensor holds vacuum, it is okay. If the MAP sensor does not hold vacuum, it must be replaced. Fig. 1: Manifold Absolute Pressure Sensor 84174020.gif

Check engine code reading ''Map Board Sensor, High Input'' and a second engine code ''EGR Sensor, High Input'' Light just came on. Vehicle is a 2005 Mercury Gran Marquis with 85,000 miles on 4.6L V-8. ...


means your egr is malfuctioning or needs to be cleaned. the high imput means the egr is allowing for exhast gases into the combustion chamber and the map code is caused by the egr as well.
