I have a code just set for the first time yesterday
sure yesterday it was PO238 map sensor voltage high, I cleared this yesterday to see what would happen today
Turned ignition on today and PO237 map sensor voltage low set, no PO238
Done the diagnostics for the 237 code and everything checks out except map voltage is 0.5v ignition on not running or running, it does increase to around 1v to 1.6v if stalled in gear
I got 5.2v on orange which tells me the 5v supply is good, no other sensor codes set
no short to earth on the other 2 wires or each other
I haven't disconnected the ecm plugs and checked continuity of these two
Fitted a quad about 2 to 3 months ago but I can't see that causing the problem, been working fine and still is
I'm going to order a Map sensor and was wondering if anyone has used a STANDARD MOTOR PRODUCTSAS334 this is £59.85 from Rockauto or am I better ordering a Cummins part ?
