SOURCE: p1613 fault code & engine will not rev over

Crank sensor or engine speed sensor is faulty.

Fault:
Irregular power loss on accelerating
The speed of the engine is limited till 2500rpm
Frequent loss of crankshaft position sensor signal

Cause:
It is caused due to leaking from thermostat housing into crankshaft position sensor harness multi-plug

Remedy:
Check and clean the crankshaft position sensor harness multi-plug contacts. Rectify the engine coolant leak from the thermostat housing if found. Take a note of the engine coolant level and monitor it for changes, showing a leak is indeed occurring.

SOURCE: runs rough under load ,stalls

Hi

one of 3 faults

1 MAF sensor also Known as air mass sensor
2 EGR valve, this is most common with the 4000 rev limit and a top speed of say 50 mph
3 air leaks or tears in air pipes or poor seals.

I would be tempted to clean both the EGR and MAF sensor before spending any money though, these parts ofetn work much lonegr when clean

Regards

Dan

High emmisions loss of power at 3000 rpm diagnostics says no fault found


You didn't mention what sort of car you have.
You can try disconnecting the electrical lead on the MAP sensor. Then give the car a test drive.

A faulty MAP can cause high emissions, erratic running and high fuel consumption.

You can also try cleaning the EGR - the exhaust gas recycler valve.

It's strange that you have no fault codes. There is no check engine light illuminated?

No power at high rpm


I'm guessing but this sounds like air problems. do you have a new air filter? The O2 sensor may be off but not technically bad yet. I'm pretty much stuck on something restricting the air flow.

Hi Steve, I suggest having a diagnostic scan carried out on your vehicle. The problem may be related to a defective operation of the Variable Valve Timing or a defective crank or cam pick up sensor. The scan should pin point the problem area without guess work. Regards John

I have a 1996 328is. After you run the engine at about 2500 rpm for a couple of minutes, it will misfire, and the reason for the misfire is it looses injector pulse to a cylinder. If you turn the car off...


The 1st thing u need to do here is run a trouble code test on the engine control system, it is called an OBD 2 trouble code test, but based on the symptom it sounds like u either have a defective camshaft or crankshaft position sensor, these sensors signal the PCM (powertrain control module) when the cylinder should receive spark and when the injectors should fire, if the signal is erratic or just stops all kinds of weird things happen, erratic fuel injector pulse for sure, but as I 1st stated a trouble code test is needed to pin down the sensor, if no codes exist hen it is poss the PCM is defective.

Reving problem on 2001 santa fe


when you try to rev it up does it sort of rev up and down like a rythm?
If so that is a safety thing to keep people from blowing up there engines. My truck does that too. It sounds like it's not getting gas at hi rpm's. Only floor it when your driving don't try to show off the rev you'll blow it

Timing at idle is more than 1000rpm


It appears the car may not be entering tuneup mode. warm up until temp is normal, idle stays below 1000 rpm
2000 rpm for 2 minutes
rev engine 2-3K three times
idle for one minute

turn off
disconnect tps
start
rev 2-3K three times
adjust timing
