Just changedCam shaft sensor changed, Montero won't start now

2003 Montero Ltd, 3.8L, just rolled 84K - NEVER had any trouble with this SUV, I love it! Last week it didn't want to start, and only stayed running with one foot on gas, other on brake, made it home luckily. Code P340, cleared code, did start and drove right into the garage. Changed sensor, horrific job, especially when hubby doesn't like the vehicle. Will not start at all now, acting like timing is off. Borrowing a better pro scanner tomorrow to run codes again. Any suggestions ? Thanks!

I presently have a similar situation,I was getting a flashing engine light and when I scanned for the DTC codes with Evoscan v2.6 set to the MUTII protocol, I was getting a Can Sensor Fault with no OBDII P code.

However I would hit the sensor with a metal and the Engine light would go off and I would get a start. This happened for several occasions about a month until I replaced the sensor with a aftermarket sensor from Ebay.Presently I am cranking the engine but it is not starting .


I am getting a 0.1 -5 Volts on the signal line of the Cam sensor at the ECU pin 88 and around 450 RPM using a Fluke meter that can measure RPM. I also checked the Crank sensor and I am getting the same voltages with 650 RPM.

I feel that the Ignition and the fuel is shutdown by the ECU with Evoscan 2.6 I am getting several faults that cam be cleared but still comes back again.I have notice that when I check the inhibit box I get a "1".when I log the engine and one of the faults is a TPS but the throttle position on Evoscan is showing 13% with my foot off the accelerator and 93% when the pedal is fully down.



Please note that my RPM gauge is not flickering and normally this would cause a no start condition.

My car is a 1998 Mitsubishi Galant with the 4g93 1800 cc engine and a MD346982 ECU, working for the past fourteen years and it is now having a no start condition that I am working on presently. I bought it used with 110,000 KM and I drive it for around 15 hours, per Month average.

My 2002 Galant 2.5v6 6A13 won't start either, not since Sept 2018. The mechanic (UK) has ordered a new cam shaft sensor, and we are waiting for it to arrive from Japan. Gulp. I'll let you know. I'm nearly at the stage where I reach for the hammer.

Does your Fluke measure frequency? That would be more interesting than just level, surely? An oscilloscope would be even better, because then you could check for a nice crisp waveform. If I ever get something running, I'll post a picture of the scope trace.

I use a Fluke 88V and it measures Frequency and RPM. Presently I got the car started after I re-installed the old intermittent sensor .
I am in the process of sourcing a new Cam sensor and a Crank sensor from Japan.
I used the car to drive to work today and no Engine light so far .

Sorry, of course your fluke measures frequency. Never mind me. But tell me about "intermittent": my car stopped a couple of times going through deep puddles December 17, then stopped while I was parking but revived just before the recovery truck came and that was February 2018. Then September 2018 it stopped while parking and has never started since. No engine warning light, no codes. Is that anything like you had?

Sorry about the late reply. I had a fault one morning I was going to work and I stopped at the Traffic Light and the car engine died on me and will not re-start. I towed it home and the next morning I just hit the Cam Sensor and secured the Crank sensor connector with some electrical tape and the car started .
I since checked the Fuel Pump and found it working but the Filter was a bit dirty so I cleaned it but when testing it outside the car with a 12 volt Power Supply I noticed something like pieces of plastic material coming out from the Fuel Pump output. I plan to change the Filter with a new one but so far the car have been working for one and a half week without codes and engine lights.

That gives me hope that a new can sensor will make my car start too! Thanks for letting me know 🙂
