DTC ) fault code ) - P1237:
Boost Control Positive Deviation

This fault code can be set when the fuel tank is empty or the specified fuel is not used. ( supermarket fuels etc have been known to cause this.. )

It can also be attributed to a turbo fault - if the fault is no turbo boost.

I would start by making sure the harness was not pinched during the install of the tank. I believe the FPMD is under the rear right seat or on that side, in the trunk.

P2106 - Throttle Actuator Control (TAC) System - Forced Limited Power Description: The TAC system is in the failure mode effects management (FMEM) mode of forced limited power. This DTC indicates the FMEM action is in effect due to a failure in an electronic throttle control (ETC) related component or module. Possible Causes:

• Unplugged motor, circuits shorted to power.
• TAC motor open, unplugged motor, circuits shorted to power.
• TAC motor stuck open or closed.
• Mass air flow (MAF) sensor fault.
• Throttle position (TP) sensor fault.
• Module communications network concerns.
• Manifold absolute pressure (MAP) sensor fault (Vehicles with an EGR system module [ESM]).
• Output shaft speed (OSS) sensor fault (Crown Victoria, Expedition, Explorer, F-150 4.6L and 5.4L, Grand Marquis, LS, Mountaineer, Mustang 4.6L automatic, Thunderbird, Town Car).
• Turbine shaft speed (TSS) sensor fault (Crown Victoria, Expedition, Explorer, F-150 4.6L and 5.4L, Grand Marquis, LS, Mountaineer, Mustang 4.6L automatic, Thunderbird, Town Car).
• Anti-lock brake system (ABS) fault (Crown Victoria, Expedition, Explorer, F-150 4.6L and 5.4L, Grand Marquis, LS, Mountaineer, Mustang 4.6L automatic, Thunderbird, Town Car).

Diagnostic Aids: This DTC is an informational DTC and can be set in combination with a number of other DTCs which are causing the FMEM. Diagnose any accompanying powertrain DTCs first. For Crown Victoria, Expedition, Explorer, F-150 4.6L and 5.4L, Grand Marquis, LS, Mustang 4.6L automatic, Thunderbird, and Town Car with only P2106, repair any ABS DTCs, ABS related DTCs in other modules or vehicle communication concerns using the appropriate section of the Workshop Manual.

Hi,
P1237 - Fuel Pump Secondary Circuit Malfunction

Googled Link:http://engine-codes.com/p1237.html

DTC P1014 - B Camshaft Position - Timing Over-Advanced or System Performance (Bank 1).
At engine start-up the control module checks that the camshaft is in the correct position in relation to the crankshaft. Diagnostic trouble code (DTC) ECM-62 is stored if the control module detects the camshaft in an incorrect position on start up.

Possible source:
Camshaft cogs incorrectly seated
Incorrectly installed camshaft pulley
Contact resistance in the terminals.

Condition:
Malfunction indicator lamp (MIL) lit
The engine misfires.



DTC P1237 - Turbo Control Valve
Looks like the turbo is not producing enough boost. Check the waste gate hoses and the waste gate itself to see if its bound up. If the waste gate is working right, I would suspect a bad turbo.

This is an advanced level repair. You may want to have Volvo do the diagnostics on this one. Your code is for low turbo boost pressure. The waste gate is a big silver actuator on the turbo. It has vacuum hoses going to it. See if they are all hooked up. Also see if you can move the lever that the actuator pushes on. If its jammed that may be your problem.


Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

You need to take it to someone that has a dynostic tester to see what DTC is activating the check engine light. It could be many things.
Autozone will do it for no cost.

P1237 - Fuel Pump Secondary Circuit Malfunction

Electronic Returnless Fuel Systems (ERFS) utilize a Fuel Pump Driver Module (FPDM) to control fuel pressure. The PCM uses a Fuel Rail Pressure Sensor (FRP) for feedback. The PCM outputs a duty cycle to the FPDM to maintain the desired fuel rail pressure. During normal operation, the PCM will output a FP duty cycle from 5% to 51%. The FPDM will run the fuel pump at twice this duty cycle, e.g. if the PCM outputs a 42% duty cycle, the FPDM will run the fuel pump at 84%. If the PCM outputs a 75% duty cycle, the FPDM will turn off the fuel pump.

If the FPDM does not out any diagnostic signal, (0 or 100% duty cycle), the PCM sets a P1233 DTC. This DTC is set if the FPDM loses power. This can also occur if the Inertia Fuel Switch is tripped.

If the FPDM outputs a 25% duty cycle, it means that the fuel pump control duty cycle is out of range. This may occurs if the FPDM does not receive a valid control duty cycle signal from the PCM. The FPDM will default to 100% duty cycle on the fuel pump control output. The PCM sets a P1235 DTC.

If the FPDM outputs a 75% duty cycle, it means that the FPDM has detected an open or short on the fuel pump control circuit. The PCM sets a P1237 DTC.
