[erwinpongslee]

hi i just picked up 2008 nissan rogue s awd with 190,000kms on it and been dealing with this codes snce i got it,checked and replaced throttle body but code still presist just want to ask if anybody had the same issue and can point me on the right direction thanks

P2119 almost always indicates a dirty Throttle Body, it happens when the butterfly doesn't return properly from an open position. The P2101 is a "catchall" code that will show up with most throttle issues, the P2119 is actually pointing to your problem. If you changed the TB already then you may have got a bad one. Did you run an IAVL on it?

[Rogue One]

Diagnostic Trouble Code (DTC) P2101 stands for Throttle Actuator “A” Control Motor Circuit Range/Performance. It is usually triggered when your vehicle's powertrain control module (PCM) detects that the actual throttle position does not match the desired throttle position.

What causes this problem with the Throttle Actuator A Control Motor Circuit?

• Throttle actuator failure
• Throttle position sensor problem
• Bad throttle control system
• PCM failure that may require reprogramming
• Bad wiring and connectors

Replace/Repair These Parts To Fix OBD Code P2101

1. Pedal Position Sensor - The accelerator pedal position sensor is monitored by the ECU and is one of those constituents which will trigger an error code in the ECU when a fault arises. It would also give rise to the illumination of the check engine light on the dashboard. Buy top notch pedal position sensor from us at economical prices.
2. Coolant Hoses/Pipes - Damaged hoses and pipes can cause leakages and thus reduce the effectiveness of the cooling system. Thus, cracked and damaged pipes must be replaced immediately.
3. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
4. Throttle Position Sensor - Are you experiencing sudden idle surges and sudden hesitation while accelerating? Then these are the symptoms of defective throttle position sensor. Get it checked and replace if needed.
5. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
6. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
7. Diagnostic Tools - It is always advisable to use correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in efficient manner. Buy new quality diagnostic tools from us today!

You should also check the loop of wire where the TB connector comes out of the harness, a fatigued wire there can cause intermittent issues. Since P2119 is a "return spring" code I doubt the problem would be with the plate power wiring, more likely in the sensor ground wire.

thanks everybody,i went under dash and found some wires thats been tapped on,but still did not solve problem,so i try to clear code with feet on gas pedal,it clears the eng.light as long as i keep my feet or keep it around 2000rpm,the vcs light stays on.i got a chance to read the throttle possition and pedal does not match throttle is at 18% and acc pedal is at 13% scan tool reads P0605,P1225 and C1130 i can read the eng light blink the codes when i do the throottle/idle reset except for the C1130 and still digging under dash thanks again

pls help thanks

[VStar650CL]

There may not be an update, but there's a function in the Nissan Consult3+ scanner for "Blank Programming" pretty much any ECM. Treating an ECM with corrupted flash like a "new" unit allows re-writing the original machine code even if there's no update for it. To do this, the Parts Department needs to look up the "ROM ID" value for your vehicle's ECM, then the tech doing the programming needs to select that value when using the "Blank Programming" function. That will usually cure a corruption issue, since flash rarely goes bad, it simply loses integrity and needs to be refreshed.

thanks vstar,can i use the same ecu?is the one out of 2010 ecm will work?if it need reflash jow much will it cause,does anybody here do this service in toronto or gta area thanks

[VStar650CL]

Any Nissan or Infiniti dealer should be able to do a blank-repro, but it's an "in the car" operation. There are specialty houses who can reprogram off the car, but we don't employ any so I can't make recommendations. I'd try recovering the corrupted one while it's still in the car to keep matters simple.

Regarding a replacement ECM, there will be a Hitachi part number on the outside of the original part, something like MEC901-180 B1. The series (MEC) and model (901-180) need to match. The B1 and any other numbers are firmware, date and manufacture codes. None of those will matter since you're reflashing the unit.

do you have inbox? how can i personnal message you? and where are you located?

[VStar650CL]

You don't have enough posts to do a PM, you need 10 before the system will let you. Maybe RogueOne can give you dispensation. I'm in central Arkansas.

[erwinpongslee]

so what do i ask the dealer?get the ecm repro or they will still run a scan?how much does it usually cost?

[VStar650CL]

Yes, I'd ask for both. Get a scan on the car and then have them refresh the program to see if it helps. Our dealership would charge you an hour for the repro and probably throw in the scan sheet.

ok so dealer want to rescan it before reprogram but im thinking if they scan and say there is something wrong with the ecm then i might aswell get the reprogram ecm flagship1 has life time warranty,i looked around and the guy i talked to said its a lie you cant get a reprogram ecm without the car, can somebody shine a light on this flagshipone said its plug and play

[erwinpongslee]

i was going to do the reprograming my self just have to get cheap laptop download nissan j2534-1 i wonder if there is a special usb and obd connector or i can use what ever can connect with obd port

Soooo, let me get this straight... your rationale for trying to reprogram it yourself is that you don't want to know what problems it might have before you blow money on a programmer?

[VStar650CL]

PS - Also get over the idea of any ECM except the one already in the car being "plug and play". If you change it, at the very least it will need to have the keys reprogrammed.

[erwinpongslee]

ok so the dealer it is will see what they will say thanks

[erwinpongslee]

so while im waiting i did test again and im not getting power on terminal 5&6 both on throttle harness and ecu did put direct power from battery ecu harrness and i can open and close tb ecm is not sending power to throttle body

[VStar650CL]

Check the Throttle Control Relay in the IPDM. The ECM has a separate power circuit for the TB, it doesn't get power from the regular ECM supply.
