guys pls i need ur help

my car, a 2008 Mitsubishi oulander 3.0 V6 XLS, wouldn't go beyond 60kph. once i get past that it switches off. if i move slowly or parked, esp. in traffic, engines also goes off. mechanic checked fuel pump, plugs, tank etc and then scanned. problem detected, ecu.

my mechanic confirmed finding a brain box with the correct part number but cant find someone to program the brain box.

- please could you help me confirm the correct part number for ecu replacement? VIN is JA4MS41X68Z002786
- can you guys help with finding a programmer who can help with fixing the ecu?

thanks

was the car scanned with a very compartible OBDII scanner? its very rare for an ECU to allow you to drive up 60kph when its self is faulty most of the time it would be the sensors

the mechanic used scanners i assume are compatible. however, what do you advise?

was the car scanned with a very compartible OBDII scanner? its very rare for an ECU to allow you to drive up 60kph when its self is faulty most of the time it would be the sensors

when scanned it gave the following codes:

code 1- P0106 BAR0O./MAP sensor range
code 2- Misfire detected

what do you advise?

if the ECU is Faulty on average you should also have a code

jaz: when scanned it gave the following codes:

code 1- P0106 BAR0O./MAP sensor range
code 2- Misfire detected

With these codes, I won't be quick to point accusing fingers at your ECU. But then, the engine shut off. Does it start presently?

Your problem looks like an easy fix and is centred around P0106

How this sensor works :The "brainbox" uses the MAP to monitor engine load, The "brainbox" PCM supplies a 5 Volt reference signal to the MAP sensor. Usually the PCM also supplies a ground circuit to the MAP sensor as well. As the manifold pressure changes with load, the MAP sensor input informs the PCM. At idle the voltage should be 1 to 1.5 Volts and approximately 4.5 Volts at Wide Open Throttle (WOT). The PCM looks for any change in manifold pressure to be preceded by a change in engine load in the form of changes in throttle angle, engine speed, or Exhaust Gas Recirculation (EGR) flow. If the PCM doesn't see any of these factors change while detecting a rapid change in MAP value, it will set a P0106.

The following could be symptomatic of a P0106:

Engine runs rough
Black smoke at tailpipe
Engine will not idle
Poor fuel economy
Engine misses at speed

How to test: with a multi meter search for ground(-) and 5v(+) at map socket with ignition on, the third pin will give varying output between 1-4.5v depending on engine load and only when engine is running and the signal sent straight to the (brainbox)pcm if you don't have the voltages I just mentioned check harness/wiring. Or better still tell us what voltage you have.

Please note:I'm assuming your (wiring) harness has not yet been abused or damaged.

Also using live data from an obdII diagnostic tool you can monitor the performance of the MAP.

Note: DO NOT use an analogue multimeter to test sensors use a digital meter please.

yes the car starts and i even drive it around town, only that i cant go beyond 60kph. moreso at other times it jerks like the car doesnt want to go on and then go off even at low speeds.

from my research of the codes i mentioned the symptoms of the car are exactly as captured under P0300 engine misfire and P0106- MAP sensor range.

i suspect its not an ECU problem but what can i do?

DECOtech: With these codes, I won't be quick to point accusing fingers at your ECU. But then, the engine shut off. Does it start presently?

thanks for your info. the mechanic used a digital scanner which gave live readings on the MAP sensor, last reading was 31kpa. i'm keeping my eyes on the other code- P0300 Random/Multiple Cylinder Misfire Detected. what do you think?

A misfire can be caused by a list of faults, but there are a few suspects that occur more than others. The normal (primary) culprits are simple spark or fuel usually soaking the spark plugs, plug wires, the coils, or the fuel-delivery system.

Other bigger causes can be ECU or wiring problems, breakage in the rotating mass (pistons, rods, crank bearings), valves and the heads can fail or distort, cooling difficulties might cause overheating, and any number of gaskets could have pushed. Most are rare and, importantly, most of the scary stuff was
probably caused by failure to address simpler problems in the ignition or injection.

The sensible method to fix this problem is to gather available knowledge about the misfire, focus on steps necessary to ELIMINATE suspects, and let the process guide you to its cause. Call it scientific method.
-GAZZUZZ has made a very good point.

thanks guys. will tell my mechanic to hold on on the ECU and lets focus on other areas mentioned.

thanks again.
