I bought a 2010 CR-V 2.2CDTI automatic second-hand last week. The previous owner, who's a friend, mentioned he'd had a clean DPF warning before the controle technique (French version of an MOT), which he'd cleared with a blast and some injector cleaner. This reappeared on my test drive, but I wasn't too concerned. However, when I got it, the first thing I did was put a litre of DPF cleaner in the tank and give her a blast to Bordeaux, which cleared the DPF clean warning.
However, five days later it was back again. I'd also noticed that the fuel economy wasn't as good as the manufacture suggested (averaging about 8.2l/100km). So this morning I plugged in an ODB2 reader and got the following messages.
- Mass air flow (MAF) sensor/volume air flow (VAF) sensor low input
- Intake air temperature (IAT) sensor -high input
- Manifold absolute pressure (MAP) sensor/barometric pressure (BARO) sensor -high input
- Throttle actuator control (TAC) motor - open circuit
- Engine coolant temperature (ECT) sensor -high input
- Intake air temperature (IAT) sensor 2 -circuit high input
- Fuel temperature sensor A -high input
- Turbocharger (TC) boost control position sensor - circuit low
- Throttle position (TP) sensor A/accelerator pedal position (APP) sensor A -high input
It seems an awful lot of sensors to go wrong independently and apparently shorts to either posiive or earth are common reasons for almost all of them. I was just wondering if there was anywhere in particular that is a likely culprit to cause all of this?
Thanks in advance.
