I am getting an OBD-II scan code of P1166, need translation.

iv seen this happens to alot of christler products, the only way iv ever found to get past this is to just use another obd2 scanner

HI,
Strongly suggest taking to the dealer as it should still be under warranty.

Code info I googled:

OBD II Fault Code P1F68 :Description of OBD II Fault code P1F68

TH2TNK Sensor Value Offset Shifting
Possible failuer of OBD II Fault code P1F68

• Hydrogen Tank Internal Temperature Sensor (TH2TNK) offset shifting
• Inlet Air Temperature Sensor (TA) offset shifting
• Offset shifting of both Teperature Sensor (TH2TNK) and Inlet Air Temperature Sensor (TA) in Hydrogen Tank
• RTC function error (Miscalculated Soak Time)
• FSVSCM failure
• FCCM failure

Diagnostic Procedure using AutoHex auto Scan tool tester

• The rear average wheel speed > 15km/h and vehicle speed on the meter<1km/h
• If the rear average wheel speed > 15km/h and VSP<1km/h lasts for 0.3 seconds, the malfunction is determined.

Test Conditions using AutoHex Scan tool tester

• Vehicle speed / wheel speed is normal
• Brake is out of action
• The automatic brake is out of action

Clear Fault codes Conditions

• The rear average wheel speed > 15km/h and vehicle speed on the meter<1km/h
• If the rear average wheel speed > 15km/h and VSP<1km/h lasts for 0.3 seconds, the malfunction is determined.

MIL Status

• Glow ON

Note:

• AutoHex is a professional OBD /OBD II diagnostic scanner / scan tool tester.
• This fault code is a GERENRIC fault code, some cars may change the meaning of this fault code.
  To get the accurate fault code description you may use AutoHex OBD scanner

Instructions
1. Plug in your OBD II (on-board diagnostics) scanner to your OBD II port, which is usually located near the steering column. Many models have the OBD II port on the left side of the under-console of the driver's side dash, near the door. If your car was manufactured prior to the 1994 production year, you may need to use an OBD I translator, which plugs into your OBD II scanner.


2. Turn on your scanner, which may require you to turn your car to the "Acc" position, and read the codes that appear. Use a manual that comes with the scanner to translate the codes.


3. Replace any sensors that come up in the OBD II scan. Multiple sensors work together in order to help fire and time the ignition process for the engine's combustion. The knock sensor particularly helps to sense the engine vibration patterns and regulate the timing in accordance, and may account for excessive engine vibration if the sensor is failed. You may need to remove several components and engine parts in order to access specific sensors, depending on your make, model and engine design. You may also need to raise your vehicle on car ramps in order to access the underside of the engine to remove and replace certain sensors.


4. Replace engine and transmission mounts if needed. This process can vary from vehicle to vehicle, however it usually involves using one or two floor jacks to support the weight of the engine while unbolting one or more engine mounts. Each engine mount also has its own insulator and rubber stopper materials, which are critical to the engine mount's functioning. Failed engine mounts do not necessarily lead to damaging other engine components and is not a fix critical to the proper functioning of your car engine.


5. Inspect your harmonic balancer, which is connected to the crankshaft via a drive belt and serves to reduce and absorb some of the vibrations caused by the crankshaft itself. Loosen and remove the drive belt by turning the belt tensioner bolt. Unbolt the harmonic balancer with a torque wrench and inspect the insulator component, which should be in good shape. Replace the harmonic balancer if the insulator is cracked or showing signs of wear and tear, or if it is missing.

hi there is no way to find out if is major or small problem
without having the Trouble Codes .you need OBD II scanner it Enables the use to read OBD II diagnostic trouble codes (DTCs) from the on-board computers.
You can get a free scan at autozone parts stores .

If it is a diesel engine then unfortunatley they are NOT OBD II compliant. They do have the OBD II port but the scanners you can use at the A/P store won't pull those code(s). You will have to use a scanner that pulls PSD code(s) or go to a shop with the equipment or the dealer.

yes, it's always active. A light will come on when it detects a fault. You can also use a good scanner to interrogate the system, actuate valves, etc.

Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check and let me know if you have questions.

yes u need a basic code reader, there is no other way on this OBD 2 system
here is one that is on ebay.

if you used a generic form of scanner, you will not get any codes. youre going to need to take it in so they can get into the rest of the system to track down the source of the problem. no obd2 is a protocol.

you need an obd2 code reader
