I did notice today while on I-10, that at a steady 65 mph and an somewhere along the lines of 2500 rpm there is a very slight pulsating feeling to the drive, as if being bumped from behind, and no, there was no cross or south wind…? The manual also mentions a “faulty regeneration switchover valve” and this would be.? Now, in my case I am not getting any codes at all, and without live feed reading I need to find a way to test and determine if my O2 sensor is working properly. Idle speed correction, (idle speed emissions level as a mixture of adaptation) is performed by the lamba control in our case.Īnother GREAT influencing factor to the injection timing is the lambda control. I would practically need to dissect the parameters influencing control:ħ.Ědaptation of fuel injection maps by means of resistance trimming plugs = Not applicable for USA/Cali ver.Ĩ. Also, could the CC create some type of conflict if not functioning properly.? I have been driving for some days now after replacing the EZL and NO DTC’s have appeared or stored for that matter.įor the above reasons, I wanted to get my hands on something out there that might help me in the diagnostics of my engine not being able to reach redline and acting up with very low torque. This leads me to believe there might be something going on with my ETA even though records show it was replaced 2 yrs ago. It states that this function goes into effect, “if the throttle valve is opened further than specified by the accelerator pedal because of a malfunction and the tempomat cruise control is not in use.” I was also hoping I could find more information there on diagnosing the Fuel Safety Cutoff by the LH module when triggered by a safety function of the electronic accelerator pedal actuator. Regarding the Diagnosis Manual Engine Vol.2, the areas which I would like to dig into are specifically related to:Ĭylinder Selective Fuel Cutoff, Ignition circuit fuel cutoff dealing with fault in ignition coil or open circuit in wire. Would this account for a fault in the rear axle vehicle speed sensor.?
In one instance the engine speed is governed 5600 rpm incase the road speed signal is interrupted.
There is a section on engine speed governing.
