Question about 1998 Volvo S70

Open Question

What code description fits P1175 & P1237 For Volvo v70 X/C? Why are there so many options to choose?

My car has stalled a handful of times, only while at a very low rate of speed turning, to nearly stopping. No other issues until the check engine light came on and threw two codes P1175 & P1237. I have looked online and found too many different results for these codes and have no idea what issue to pick! For P1175; Is it a Cam Control Fault, a Long-term fuel trim Lower Limit, or a Fuel Trim Adaptation Inactive Bank 2 Malfunction? For P1237; is it a Fuel Pump Secondary Circuit Malfunction, an accelerator position sensor, a Turbo Boost Solenoid, or a Turbocharger control system flow fault Flow too low?

SOURCE: what does fault code ECM - 250A long term - fuel trim:upper limit on 2004 volvo S40 mean

Sound like a problem with the MAF sensor, try replace.

Pulled codes for ECM-250A long term fuel trim upper limit, inspected and found air mass sensor failing internally, should show 4 f/s at idle and is showing 2.98 f/s at idle. Recommend replacing with new.

SOURCE: What do codes P1175 & P1237 actually mean? Why are there so many options to choose from? How can I actually repair it?

The ECM has numerous sensors that are read continuously and these results are checked against pre-set parameters in the CPU memories. Every possible cause of a fault code is an associated sensor that is being affected by the fault so there are several possible reasons that cause the fault . That is to say wiring is a possible cause ---the unit itself is another possible cause---low /high voltage is another and so on. Take it to a service centre as with most makes of vehicles there is a common fault problem that experienced technicians are aware of and can pin point quickly. As with advice from readers the causes are general areas of advice to look at so if it appears confusing then take it to an experienced shop.

Idle speed too low


Sounds like you may have an issue with your idle air control or your mass air flow sensor. The IAC can cause a vehicle to stall when up to temperature, especially when warmer outside.I would clean or replace that for starters.

Stalls sometimes when stopped at lights engine misses at stop


Engine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

2001 vovlo v7o xc trouble codes p0014 and p1237


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.
