2021年5月21日 · P0652- Sensor reference voltage 2 circuit low. This sucks! You get a lovely CEL and you get the lightning bolt on your dash. I experienced loss of power and terrible fuel economy. Was rather ANNOYING. This truck is a 2018 has 305k miles. My issue turned out being my EGR back pressure sensor...

2011年6月10日 · P0652 5-Volt Reference 2 Circuit Low Voltage Possible Causes Setting Conditions 5V reference circuit is open or shorted to ground One or more of the devices (listed above) that connects to the circuit has failed ECM has failed Engine running; and the ECM detected the 5v Reference 2 signal was less than 4.70v for 2 seconds.

2010年10月18日 · I was driving to work today going up a pretty steep hill and my truck started to drive very rough. It would not accelerate without that "hiccup" popping. I read the DTC's and the only one was P0652. It says 'Sensor Reference Voltage 2 Low". Can someone tell me what sensor this is and how I can...

2019年2月19日 · Getting the P0652 code. I’ve checked batteries changed mass air flow sensor, crank position sensor, cam position sensor and exhaust back pressure sensor. When I changed crank position sensor it fired up and ran great killed it and then a few minutes later went back to start it to move it started fine and ran good for a few minutes then all ...

2020年10月8日 · About a month ago my truck wouldn't start and I narrowed it down to blown up FICM. A month later I found a FICM and the truck starts right up, However I have a P0652 Sensor Reference Voltage B Circuit Low and the truck is in the limp mode. I've measures the reference voltage and it is low, it's 1.73V.

2014年4月23日 · P0652-sensor Reference Voltage 2 Low P0192-fuel Pressure Sensor Low P1507-crankcase Filter Restriction P1508-crankcase Filter Restriction - Replace Filter Engine surging a lot and almost stalls at idle. AHHHH!!! Any other ideas? This is a really stupid design to put all of these sensors on one 5v source.

2017年2月26日 · Perform a voltage drop test on the grounds. But because P0652 is a 5v ref circuit, any of the components on that circuit can cause this code to set. The APP sensor 2, A/C pressure sensor, Oil pressure sensor, and fuel rail pressure sensor can have a circuit with a chafed wire in it causing concern. Or even the sensor itself could be faulty.

2019年6月24日 · P0652- Sensor reference voltage B circuit low voltage It’s only throwing these codes once i put the truck in gear (park or reverse). It was doing it in park once the truck warmed up, but now is mainly just doing it when put in gear.

2015年6月29日 · The truck actually got worse... While cranking, it just barely fires for a few seconds and goes dead. I kept cranking on it with a battery charger attached and now the P0341 has went away. However, now I have a whole new slew of codes: P0192, P0652, P0107, P2228... Please help guys!! Thanks in advance

2011年10月1日 · Got a P0652 wednesday night and cleared it. It stayed off for a while but came back. Thursday on my way to work it came on again and I lost power. It also threw a code for fuel rail pressure too low. On my way home from work it cut off twice. Started throwing the P0341 cam sensor code. I changed...
