B. Crank the engine for 5 seconds. C15 Acert 06 MXS1445 Have put 6 front and 5 rear injector harness in. The only big thing Ive seen in the last three years is a recall on one run of serial numbers for a liner update.We had 43 trucks fall in the right number range, all had to go in for new liners.Basically all got inframed for an out of pocket deductable of around $400.00.Not bad, except for the downtime.Mine was done last year, had new nozzles at that time.Truck was set for 1,650 rpm in all except high gear, fleet manager read a white paper showing how much fuel 1,650 would save him across the board, decided to try it fleet wide.Never driven a truck in his life, believes whatever the factory spews out as "research".Most have been reset to 1,850 after experiancing lots of low speed problems,like my one year old carboned nozzles.Had an increase in turbo losses, increased oil consumption,ect..Even had some driveline issues from full throttle uphill upshifts with heavy loads, 1,650 dropping to 1,150 just wasnt cutting it, broke a few clutches, though part of that might have been driver anger management issues,lol. Step 5: Repeat with all injector wiring harnesses. Turn the keyswitch to the ON position. I need help. I  have been bitching and complaining for TWO summers over the same symptoms. Results: OK - The injector may be faulty. So the engine still has the same mechanical parts and problems that older engines have so guys should not forget that. C. Inspect bracket (3) .

Search "" Close search Cancel. York, Ontario Truck Year 2004. so what can i do? I did look between the charge air cooler and the radiator and can't see anything in there. Disconnect the engine harness from the sensor. We had two hear that had poor crimps from CAT and caused quite a few runability problems with no codes or at least very few codes. Start the engine and run the engine. Resistance: 75 to 230 Ohms, E. For the secondary engine speed/timing sensor, measure the resistance between terminal 2 (secondary engine speed/timing +) to terminal 1 (secondary engine speed/timing -). Appreciate with any help. Illustration 3 g02207317 Temp goes up to 210 the the fan kicks in. Sorry that i made new thread. Verify that the problem is resolved. Schematic for the engine speed/timing sensors. The loss of the signal from both of the sensors during start-up will prevent the engine from starting. was normal and it was unbelievable how much better it ran. B. If the engine will not start, monitor the engine rpm on Cat ET while the engine is being cranked. Perform the following procedure for each sensor. The engine will shut down only if the signals from the primary engine speed/timing sensor and the secondary engine speed/timing sensor are abnormal. C13, C15, and C18 Engines Troubleshooting – Speed Control – Test, C13, C15, and C18 Engines Troubleshooting – Variable Valve Actuator – Test. If the engine was running before removing the sensor, reinstall the sensor. Is your cylinder head failing? The harness and wiring are OK. The voltage is 3.0 ± 0.2 VDC. 3 0. A lower reading means there is excess resistance in the wire somewhere. 3,775 satisfied customers. There is a problem in the harness wiring. They pressure washed and flushed everything. Return the unit to service. Expected Result: One or more of the following diagnostic codes has been logged: 1-11 2-11 3-11 4-11 5-11 6-11 Results: OK - There are logged diagnostic codes for the injectors. More Info. C. Remove the sensor. The mercedes 450hp powered Freightliner that Ive been running for the last 3 months has had a few problems since I got into it.Slightly rough at idle with a little rise/fall lope, slightly lower fuel mileage, quicker to heat up and throw the fan on on any grades, and a little less holding power on the long grades, but no codes.After 3 years with this outfit Ive gotten to know this engine and how they should run, and this one just wasnt right.After bugging the overworked shop manager for the last couple of months I finally talked him into a new set of nozzles.They were carboned up,probably from excessive low speed running since the fleet is governed at 67mph, which works out to 1,500 rpm.Problem cured, runs like a different truck.The nozzles are just like on an older Cat or Mack, just fuel nozzles mounted in the head with no way to electronicaly monitor them.Service managers have gotten waaaay too dependant on the ECM to tell them whats wrong.Theyve forgotten how to troubleshoot the mechanical end of things.

Oil looks ok on the dip stick but this is on the front axle under the breather tube. B. Visually inspect the sensor and the sensor assembly without removing the sensor assembly from the engine. Do not switch the positions of the sensor. Result: The voltage was not OK for at least one of the measurements. Inspect the housing for a cause of the sensor damage. Check the sensor tip for any damage. Illustration 2 g01180490 Result: The resistance measurement for the sensor is within the specification. Both sensors detect the reference for engine speed and timing from a unique pattern on the camshaft gear. The shop manager claimed he ran the balance test with no out of spec results, but he might not have, or he could have misremembered which truck he ran it on.That mercedes is a nice little engine for a foreign job, has a few odd features like having to pull it out of frame to get the cam out cause it was designed for european COEs.Ive heard the ECM has some good features.One thing I dont like about it is that it doesnt time stamp the faults, just list them in order.Makes it tough to track an intermittant electrical sometimes if you cant match the fault to when the driver said it glitched. Look for these codes on Cat ET: Replace the sensor assembly. Make any necessary repairs. Problems like yours are wiring related 99.99% of the time. http://www.miltoncat.com/Pages/default.aspx. and Scarbourough,Me., good guys, pretty sharp.If its under warrantee, and they find something, he wont be out of pocket on it.John.
