Ошибки 31 и 44

[Zloff]

44 - понятно, а вот 31 - подскажите, куда смотреть?

DTC - 31 Wastegate solenoid circuit error
DTC - 31 Gear Position Switch (PRNDL) error

Как я лично понимаю: обеднение смеси ("лишний" кислород) при открытии клапана EGR См целостность трубки от EGR к впуску и прокладку клапана EGR

что-то неправильно про 31, вот переводите:
31 PRNDL indicates a gear other than park or neutral for 13 seconds for 3 consecutive startups when ignition was on, engine was off and vehicle speed was 0. Or the PRNDL status indicators (A, B, C, P) showed an incorrect combination of Lo and Hi for more than 10 seconds.

31 PRNDL...

31 PRNDL это ошибка АКПП, а никак не пензамозга

я не против...
92-95 3.8L VIN L
13 Oxygen sensor voltage stays between 0.35 and 0.55 volts for 30 seconds when the TPS signal was above 0.55 volts. The engine had been running for at least 40 seconds with an engine temperature above 110° F.
14 Coolant temperature sensor signal indicates a temperature of over 284° F for 4 seconds after the engine had been running for at least 10 seconds.
15 Coolant temperature sensor signal indicates a temperature colder than -36° F for at least 4 seconds after the engine had been running for 2 seconds.
16 Charging system voltage was either below 9 volts or above 17 volts for 10 seconds.
17 PCM did not detect any spark reference pulses within 240 fuel control reference pulses (80 crank revolutions) while engine was running below 1200 RPM.
21 TPS voltage was above 0.8 volts for 5 seconds when engine was running and air flow was less than 15 gm/sec, or the TPS voltage was over 4.8 volts at any time.
22 TPS voltage was under 0.2 volts for 4 seconds when the ignition was on.
23 Inlet air temperature sensor signal showed an air temperature of -29° F for 4 seconds.
24 Vehicle speed sensor signal showed less than 3 MPH for 2 seconds when engine speed was greater than 3000 RPM and transmission has not been in park or neutral for more than 4 seconds. Or vehicle speed goes from above 18 MPH to 0 in less than 2 seconds without applying brake.
25 Inlet air temperature sensor signal showed an air temperature of over 218° F for 5 seconds when vehicle speed was greater than 35 MPH.
26 Quad-Driver sense voltage shows a low voltage when battery voltage should be present, or if the sense voltage shows battery voltage when a low voltage should be present for at least 5 seconds when the engine was running.
27 2nd gear switch was closed or grounded for 10 seconds when vehicle was in 4th gear, or 2nd or 4th gear switch was open when engine was first started.
28 3rd gear switch was closed or grounded for 10 seconds when vehicle was in 4th gear, or 3rd or 4th gear switch was open when engine was first started.
29 4th gear switch was closed or grounded for 10 seconds when vehicle was in 4th gear, or 4th gear switch was open when engine was first started.
31 PRNDL indicates a gear other than park or neutral for 13 seconds for 3 consecutive startups when ignition was on, engine was off and vehicle speed was 0. Or the PRNDL status indicators (A, B, C, P) showed an incorrect combination of Lo and Hi for more than 10 seconds.
34 There was no MAF signal for over 4 seconds while engine was running.
36 Transmission solenoid "B" has failed in the Off position which caused transmission to be in 3rd when 1st gear was desired, or solenoid "B" failed in the On position which caused transmission to be in 1st when 3rd gear was desired.
38 The Torque Converter Clutch portion of the brake switch was open and caused the TCC to be inoperative.
39 The Torque Converter Clutch portion of the brake switch was inoperative for 30 seconds causing vehicle speed ratio to be outside of its window of operation.
41 Cam sensor signal was not received by PCM for the last 5 seconds while engine was running.
42 The EST signal did not change when the ECM applied bypass voltage to the ignition module.
43 Knock sensor signal was either above 3.5 volts or below 1.5 volts for at least 20 seconds.
44 Oxygen sensor voltage was under 0.25 volts for up to 4 1/2 minutes of closed loop operation.
45 Oxygen sensor voltage was over 0.75 volts for 2 minutes in closed loop operation with a throttle angle between 0.6 and 1.9 volts.
47 Momentary loss of power to Body Computer Module (BCM). Check that PROM is fully seated. (1993 Riviera only)
51 MEM-CAL error.
54 EGR #2 solenoid was out of range for 6 of 8 tests.
55 EGR #3 solenoid was out of range for 3 of 5 tests.
56 Quad-driver voltage was incorrect for 5 seconds on the circuit connected to QDM "B".
57 Boost control solenoid did not open bypass valve causing engine torque to be too high.
63 EGR flow was incorrect. EGR solenoid did not work properly.
64 EGR flow was incorrect. EGR solenoid did not work properly.
