Engine codes P0101 and P0170

Code P0101 Meaning. The mass air flow (MAF) fault

P2188 (Fuel system too rich at idle) MAF FAULT

If it's still throwing that MAF code with a new MAF, then your problem is likely a dirty throttle body.

Here's a link for code P0101, http://repairpal.com/OBD-II-Code-P0101 Here's the link for code P 0300. P0300 OBD II Trouble Code If you fix code P0101,the other code will be fixed.Here's a new part. http://www.autozone.com/engine-management/mass-air-flow-sensor/cardone-reman-mass-air-flow-sensor/nissan-datsun/sentra/2006/4-cylinders-c-1-8l-sfi-dohc/946979_0_0

The intake air temperature sensor on a 6.6L diesel is part of the mass air flow sensor, located just outside the air filter housing, in the intake air snorkle going to the engine. The other one is for the turbo system and is located directly at the top of the engine in the inlet pipe for the turbo. This on is the intake temperature heater / sensor, and will set a totally different code relating to the turbo. The one you want is incorporated with the MAF sensor. Usually code P0101 sets.

P0101 Mass or Volume Air Flow Circ Range/Performance 16485
TSB Number: 3068 NHTSA Number: 10009606 TSB Date: n/a Date Added to File: October 8, 2004 Failing Component:Engine And Engine Cooling:Engine:Gasoline:Turbo-Charger Summary:Oil seepage from turbo air charge cooler hoses or hose blowing off during acceleration. Possible diagnostic trouble code P0299. Updated 04-24-07.there you go good luck

tHIS WILL TURN ON AND KEEP THE CHECK ENGINE LIGHT ON, MOST OF THE ENGINE BLOCKS ARE THE SAME BUT ARE BUILT A LITTLE STRONGER TO WITHSTAND THE TURBO, IF HE CONNECTS THE TURBO AND YOU DONT BEAT ON THE MOTOR I THINH YOU WILL BE OKAY, HAVE HIM USE ALL THE OLD PARTS LIKE INTAKE INJECTORS OIL PAN EXHAUST MANIFOLD AND I THINK IT WILL BE FINE, HOPE THIS IS HELPFUL,

bigger is not better when it comes to turbo units as Leyland found out when they fitted a turbo to a 690 diesel that resulted in the destruction of the engines and damage to the company reputation of a reliable engine manufacturer
Subsequent engineering found that a much smaller turbo produced more power without the destroying the engine
The turbo fitted to the engine originally is the correct unit for the maximum power that the engine mechanicals can handle
What you have to do is to ensure that the variable vanes of the turbo are working correctly and there are no boost pressures lost from intercooler leaks and loose hoses
Run the fault codes to determine sensor and actuators for the existing turbo are fully operational

P0236 Turbocharger Boost Sensor A Circuit Range/Performance

P0171 System too Lean (Bank 1)

P0237 Turbocharger Boost Sensor A Circuit Low

P0101 Mass or Volume Air Flow Circuit Range/Performance Problem

i would start, given these codes, to look around the air duct assembly for signs of cracks or disconnected hoses resulting in a vacuum leak.

There are 3 engine choices in the 98 volvo v70. All are 5 cylinders, 1. 2.3L turbo
2. 2.4L MFI DOC
3.2.4L Turbo
#2 is the most common engine for that year and model. If your engine doesn't have a turbo, that's the one u have.
