2000 V70 XC SE - Stalls When it Gets Warmed Up

Post by timothyj77 » Fri Oct 11, 2019 6:44 pm

Car runs fine for a bit then stalls out. Will restart after about 10 minutes then stalls
again further down the road. Getting code P1133 O2 Sensor Heating Circuit Bank 1 + 2 - Sensor1 Electrical Malfunction.

Had a similar issue about 6 months ago and replaced the fuel pump relay and it drove fine for a while (but no code that time).

Welcome ! I am having restart issues with my 2000 S70 after its up to temperature . Hasn't stalled yet . I get no codes , but reading your post gives me another area to check ( 02 sensors) . If you have a salvage yard near , pick up 02 sensor for a few bucks and see what happens .

Check your fuel pressure at the fuel rail. Could be a failing fuel pump...

Volvo or aftermarket relay? 6 months is about the lifetime of aftermarket ones

It was aftermarket from Autozone. Was traveling and had to get something quick.

Check for air leakage in the exhaust system and defective wiring.

ECM-280A (P1132) Front heated oxygen sensor (HO2S), signal deviation .

Conditions
Probe monitoring begins after probe preheating diagnostics are complete. Diagnostic trouble code (DTC) ECM-280A is stored if there is a fault in the front heated oxygen sensor (HO2S) or its wiring causing the signal to deviate from its permitted range
The control module registers four different types of fault:

Signal too high
The control module compares the front and rear adaptation values. A diagnostic trouble code (DTC) is stored when the values deviate by more than 3%. Note! The fault may be in the front or rear heated oxygen sensor (HO2S) circuit.

Signal too low
The control module monitors the aging of the probe by checking its dynamics when switching between lean and rich mixtures. The diagnostic trouble code (DTC) is stored if the control module registers that the probe is operating too slowly.

Signal missing
The control module monitors cross-induction from the probe preheating. Diagnostic trouble code (DTC) is stored when cross induction exceeds the permitted value.

Faulty signal
A diagnostic trouble code (DTC) stored when:
the control module registers that the signal from the front probe is above 4.8 V for too long
the signal from the front probe does not deviate from λ= 1
the signal from the front probe is showing a lean fuel mixture while the signal from the rear probe is showing a rich mixture
the signal from the front probe is showing a rich fuel mixture while the signal from the rear probe is showing a lean mixture.


Substitute value
The rear heated oxygen sensor (HO2S) control is disabled
Three-way catalytic converter (TWC) diagnostic is disabled

Possible sources
  • Signal too high:
    air leakage in the exhaust system
    short-circuit to power supply or ground in the signal cable (+) or supply cable for pump current
    defective heated oxygen sensor (HO2S)
Signal too low:
  • the cable for calibration current and the cable for pump current are short-circuited to each other
    open-circuit in signal cable (-)
    open-circuit in cable for calibration current
    defective heated oxygen sensor (HO2S).


Signal missing:
  • signal cable (+) and signal cable (-) short-circuited to each other
    one of the cables for heated oxygen sensor (HO2S) preheating is short-circuited to the probe's other wiring
    defective heated oxygen sensor (HO2S).
Faulty signal:
  • short-circuit to supply voltage or ground in signal cable (+)
    short-circuit to supply voltage or ground in signal cable (-)
    short-circuit to supply voltage or ground in pump current cable
    short-circuit to supply voltage or ground in calibration current cable
    open-circuit in signal cable (+)
    defective heated oxygen sensor (HO2S).
Fault symptoms
malfunction indicator lamp (MIL) lit.
