2001 E320 4matic wagon. the problem rose just few days ago. it just shut off while at a stop light, also shuts off while driving . it cranks but does not run, after an hour or so it starts and runs for a little while and then dies again, starts back on and runs after an hour. I have changed the fuel pump but no effect. I've been getting message "service passed due 45 days"(did service but the dealer did not reset the service indicator. Also, the engine light been on for several months, could it be mass air flow sensor that causes this problem? I appreciate your inputs. :bowdown:
The car shuts off while driving.

Buy Bosch. That $100 is too much....ask your local dealer. I buy em for $40 all day long at my dealer...and that's without my shop discount.
They will tell you which sensor your car will take, the one with one notch, or the one with two based on your vin.

Please return the unused Autozone part if you can - that is a China made part known not to be reliable.
Genuine/correct Bosch only - or you will have the problem again - quite soon.
A part warranty doesn't help when it happens agaon on the road..

After it cuts off, and you can restart the car immediately after (engine at operating temperature), it probably is/was not due to the CPS. The CPS defect usually makes you wait for the engine to cool down.
It sounds more like an electrical problem, as if you turned of the ignition ? It could be a flaky K40 relay module (especially if everything is running great then ... sudden cut-off).
BAS coming on is likely due to the cutoff, not the cause.

Yes, everything is running great and then it cuts off while driving. This is what Autozone told me after running a diagnostic: Code given PO221, Throttle pedal position TPP sensor/switch "B" circuit range/performance... Explanation Open or short circuit condition... Probable cause Poor electrical connection; Faulty TPP sensor; Faulty throttle value control module.
I'm watching this thread as my e320 sedan 05 has been stalling (always starts back up immediately). The CEL has been on well over a year. I changed the CPS and cleaned the MAF two days ago. CEL is now off and throttle response seems improved. Wife took car to Autozone today-no codes present. Can't believe it as I did not (could not) clear any. I have not driven car yet-wife is not sure it's better. Since she thinks cars are powered by unicorn farts I will have to drive it.
Next steps-clean throttle body (suggested in this forum) and change plugs (overdue at 128k).
Interesting (to me) part here is CEL went out.

Hmm, that is odd. Assuming you used a good CPS ( @CassC and @petrabid), then there's very few things left that could cause the car to simply shutdown midway.
K40 relay on W210, EIS on the W211...
...other than that, a loose MAF connection will do that. Some cars, if you unplug the MAF while it is running, it'll shut off immediately. I haven't seen this on my 97 E320 or 98 E300D, but those cars use a different engine and different engine management modules, so.... you guys could try that. Start the car, then unplug the MAF plug. See if it shuts down. You should have a code reader handy, because once you unplug, the CEL will come on. Plug it back in after your little test, clear the codes and be on your merry way.
A bad throttle body (if the IAC in it is really gunky) or if it closes completely when it is not supposed to, or an intermittent fuel pump cut out.
In CassC, that code refers to the accelerator pedal sensor, which is NOT the throttle body, but the little sensor that is next to the brake booster.
The CEL going out is fairly normal. The ECU constantly monitors the engine and whatsnot. If after a certain number of start cycles (ie. shut off, cool down engine, start, run, shut off, rinse and repeat) and the problem does not show up, the ECU will turn off the CEL and clear the codes. By itself.

I used a German made CPS (I think it was Bosch) not the cheapest I could have bought. Car is/was stalling on stops and slow turns. Fuel pump is supposed to be new as of last week thanks MB fir extending warranty to 15 years.
I've noticed a tick in the power steering and am just remembering these cars have PS filtration systems (filters) right? As ignorant as it may sound I'm wondering suddenly if the PS fluid may not be flowing well at times of added torque/demand such as stopping/turning ( at low speeds). The pump may therefore be dampening the engine? That may sound as stupid as a hat full of monkeys but I'm basically just grabbing at straws here anyway.

No, I highly doubt that. If that was the case, there's no way you could've missed it...primarily because the belt would shred itself before the car would shutdown. By then you would have no water pump, no alternator, no power steering.
Are you or your wife the type to have a million keys on your key ring? That could weight down and cause damage to the ignition. Chevy had to issue a recall for precisely this reason. Their cars would shutdown randomly too.

I believe the code is a pending code, else you would have seen the CEL. If you have this code the car usually goes into the limp mode, sluggish acceleration, etc.. does not usually cut off..
Is your car cutting off when accelerating ? decelerating or at stop lights ?
Sometimes a MAF can develop a certain failure mode that causes P0221.
No. My car literally shuts off while driving. Not when starting to drive nor stopping at a light or stop sign and not when slowing down. It shuts off while driving. Should I buy all these?
1) Throttle accelerator position sensor; 2) Throttle valve control monitor; 3) Accelerator pedal position sensor, 4) Electric throttle control acuator?
-- if it's just loose electrical wiring can't they just fix that easily?
