What does p0121 mean in engine control module?
What Does P0121 Mean? Your TPS “A” Circuit has an expected output voltage range, as does your TPS “B” Circuit (if so equipped). When code P0121 occurs, it means that your Engine Control Module (ECM) recognized that your throttle position “A” circuit’s expected output voltage has either gone above or below the sensor’s expected range.
What does the Mercedes Benz p0101 error code mean?
Ever started up your Mercedes and wondered what the P0101 error code means? If the malfunction indicator light (MIL) appears on your Mercedes Benz dashboard, this indicates the car’s on-board diagnostics sensor (OBD-II/OBD 2) has identified a problem regarding the mass air flow sensor (MAF Sensor). What is the Mass Air flow (MAF) sensor?
What does the OBD code p0120 stand for?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0120 is the generic OBD-II code which indicates that the Engine Control Module (ECM) has seen the TPS sensor circuit A output voltage going below or above the sensor’s expected range, or is chattering when compared to TPS sensor circuit B.
What happens when you put a p0120 code on an ECM?
The P0120 code will put the engine ECM to go into a failsafe mode, which will cause various drive complaints until repairs are done. For example, lack of acceleration, high idle, bucking or jerking, limited speeds, and possible stalling depending on the manufacturer failsafe mode strategy. What repairs can fix the P0120 code?
What Does P0121 Mean? Your TPS “A” Circuit has an expected output voltage range, as does your TPS “B” Circuit (if so equipped). When code P0121 occurs, it means that your Engine Control Module (ECM) recognized that your throttle position “A” circuit’s expected output voltage has either gone above or below the sensor’s expected range.
How much does it cost to repair a p0121 Mercedes?
The cost of diagnosing the P0121 MERCEDES-BENZ code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
What’s the fault code for a 2001 Mercedes Benz?
Click to expand… For the ML class it does not apply to the 2001 models. Also the fault code in the bulletin is for DTC B9103 and DTC B9123. No others would be covered by the DTB. Post # 34 in this thread lists the DTB the parts, and all affected models.

Why is my VW p0121 throttle position sensor not working?
The reason is because scan tools take samplings of many different readings over just one or two data lines and can miss an intermittent drop out. Hook up your oscilliscope and watch the signal. It should sweep up and down smoothly with no drop outs or spikes. 3. If no problems were noticed, perform a wiggle test.
What does diagnostic trouble code DTC stand for?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
