There are 3 wires from the MAP to the ECU

Brown is E (Ground)

Yellow is VC to VCC (sensor to ECM)

Light Green with a Red tracer is PIM to PIM

Hope this helps. Thnaks for choosing FixYa for assitance.
A FixYa rating from you from my answer would be appreciated.

Ecm failure causes


no year?, hopeless.
my wild guess, cell; phone?
and 1983 Accord, with ECM flash code 13?

did you look here first then ask questions.
http://www.troublecodes.net/honda/

this is a Carb car right?
if car is EFI
13 means bad baro sensor, in non science terms
that means a bad MAP sensor.
the MAP is used to calculate all air flowing in to the engine
and this allows the ECU to inject a perfect fuel mix.
if 13 happens the eCu goes to limphome and sucks fuel like crazy.
13, means bad wires to MAP or bad MAP or bad vacuum line to MAP.
a tech, checks all 3, and then tests the MAP and the problem is solved. the FSM is free, ask.

really a 1983? very very old.... tjhat...

I need to know the drive cycle for my 2001 elantra .I had code PO105 that is fixed but it wont reset


P0105 = Manifold Absolute Pressure Sensor Circuit Malfunction
I assume the code will not clear when you try to erase it? Either the circuit (wiring) is damaged, or the ECU memory won't reset/erase the code. If you know the wiring & MAP sensor are ok, try zero-ing the electrical system (disconnect the negative battery cable and connect a wire to the negative battery cable & connect the other end of the wire to the positive battery cable for 30 seconds. Remove the wire & reconnect the negative battery cable to the negative battery post. Now, this shoud have erased the memory in the ECU and there should be no code(s) present. If the code is still there, (and there's nothing wrong with the wiring between the MAP sensor & the ECU), the ECU is faulty.

Check engine light comes on and it sends a code sayin the throttle position censor, replaced it but still sputters and shifts down on its own.


What was the code? Basically all the sensors are linked together in some way, For instance the MAP sensor needs a certain reading, it then sends the signal to the ecu which will then tell the TPS sensor.. ok you need to do this. but if it was a code like tps sensor low voltage or high input or somthing, its likely an indication of a wiring problem, and bad signal from another sensor, or the ecu

1989 jaguar xjs v12 fuel mixture


Chances are the coolant temperature sensor or its wiring have failed, or the vacuum line to the MAP sensor is leaky or broken (I believe the V12 in '89 guise uses MAP sensors). The MAP sensor measures Manifold Absolute Pressure. Along with this pressure the ECU looks at engine RPM. It also measures air temperature. Knowing pressure and temperature we know density, and knowing engine speed tells us how much volume of air is going through the engine. All of this together is computed into air mass and is used to calculate how much fuel mass should be admitted. If the vacuum line is broken, the ECU reads less vacuum and produces rich mixture thinking that the engine is under high load.

Map sensor wiring for Chevy s-10


Well after looking it up it's the the map input wire is light green on both 4 and 6 cylinder models.

On a 4cyl the map has black gray and light green, the black is ground, the gray is a 5 volt refrence from the pcm(power control module), and the light green goes to to ECU for MAP input.

On a 6cyl the map has black gray and light green, the black is goes to the automatic transmission, gray is a 5 volt refrence from the pcm(power control module), and the light green goes to to ECU for MAP input.

Hope this helps and good luck

Map sensor


HI
the (MAP) sensor is one of (ECU) engine control unit sensors
it was determine the engine manifold pressure and send it as electrical signal to the (ECU) to calculate the air volume & fuel injection to the engine
